Introduction
In this article you will learn how to perform DataGridView CRUD(Insert/Update/Select and Delete) with Image save to SQL Server using C#.
This article will explain:
- In this sample demo we will learn in detail of how to perform CRUD operation for Student Profile Management using DatGridView WinForms.
- How to Upload and Insert /Edit Image for Students to SQL Server Database.
- How to display Images from SQL Server to DataGridView Image Column.
- Edit and Delete Image column in DataGridView.
- Create DataGridView Dynamically using my DataGridview Helper Class. (Refer to DataGridView helper Class Create a DatagGridView helper class using C# )
- We will be using DAL Class and BizClass for performing CRUD Operation.
- How to display Round Shape Image to the DataGridview Student Profile Image Column.
Prerequisites
- Visual Studio 2015 - You can download it from here.
Building the Sample
*Create Database and Table
We will create a StudentDetails table to be used for the Student Profile CRUD Operations. The following is the script to create a database and Table query. Run this script in your SQL Server. I have used SQL Server 2014. *
--Script to create DB,Table and sample Insert data
USE MASTER;
-- 1) Check for the Database Exists .If the database is exist then drop and create new DB
IF EXISTS (SELECT [name] FROM sys.databases WHERE [name] = 'StudentsDB' )
BEGIN
ALTER DATABASE StudentsDB SET SINGLE_USER WITH ROLLBACK IMMEDIATE
DROP DATABASE StudentsDB ;
END
CREATE DATABASE StudentsDB
GO
USE StudentsDB
GO
-- 1) //////////// ToysDetails table
-- Create Table ToysDetails ,This table will be used to store the details like Toys Information
IF EXISTS ( SELECT [name] FROM sys.tables WHERE [name] = 'StudentDetails' )
DROP TABLE StudentDetails
GO
CREATE TABLE StudentDetails
(
std_ID int identity(1,1),
StudentName VARCHAR(100) NOT NULL,
Email VARCHAR(100) NOT NULL,
Phone VARCHAR(100) NOT NULL,
Address VARCHAR(100) NOT NULL,
IMAGEs varbinary(MAX)
CONSTRAINT [PK_StudentDetails] PRIMARY KEY CLUSTERED
(
[std_ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
select * from StudentDetails
After creating our Table we will create a Stored Procedure for our CRUD Operations.
-- 1) Stored procedure to Select Student Details

Description
** Create your MVC Web Application in Visual Studio 2015**
After installing our Visual Studio 2015 click Start, then Programs and select Visual Studio 2015 - Click Visual Studio 2015.
Click New, then Project, select Windows and Select Windows Forms Application. Enter your Project Name as “DatagridViewCRUD” and Click ok.
https://code.msdn.microsoft.com/site/view/file/145635/1/0.PNG
After we have created our WinForms Project. Now we will create a Folder named as “Images” to add image and “Helper” for creating our DataGridView Helper Class, SQL BIZ and DAL Class from solution Explorer for. Add all the Images to the project Images folder. And also add the main images like Edit and Delete as Resource file.
https://code.msdn.microsoft.com/site/view/file/145636/1/01.PNG
1. Creating DatagridView Helper Class
For how to creating the Helper Class and its uses kindly Refer to DataGridView helper Class Create a DatagGridView helper class using C#
Add a new Class named ShanuDGVHelper.cs to the Helper folder. Copy and paste the below code inside the helper class.
Check for your Namespace name if your namespace name not matched with the class file then change it your namespace name. For Example here our project name is DatagridViewCRUD so you can see in the namespace it will be as “DatagridViewCRUD” .If your project name is different than kindly change it.
The complete details of the helper class can be found from the above link.
Note here in this class file for image columns the resource file will be used.in case your resource file name is different than change it.

2. Creating DAL and Biz Class
- **Business logic: **Here the Business logic is a class. From the UI (our code behind) we pass all our input from the user to the Business Logic class as objects.
- **Data Access Layer: **From the Business logic Class we pass all the object parameters to this Data Access Layer Class. This class will use the ADO.Net objects like Command (Select), Command Type (Query type is text or Stored Procedure), ExceuteNonQuery (perform Insert/Update and Delete), ExecuteDataset (return select statement) and ExecuteScalar (to return single data).
For creating DAL Class right click our Helper folder and add new Class file and give the name as SQLDALClass.cs.
Copy the below code and paste in the DAL Class.AS we have already seen if the Namespace is different then enter your namespace.
Note: In this class file I will be creating a text file for storing the SQL Connection string. Kindly change the connections string with your SQL Connections.

For the Circle Image display we will be using DatagridView CellFormatting Event and for Edit/ Delete we will be using CellContentClick event.
**Circle Image to Display in Grid: **
In the DatagridView CellFormatting event we check for the Student Image Column. We pass each Student Image to MakeCircleImage Method to display the student’s image in circle shape inside DataGridView.
https://code.msdn.microsoft.com/site/view/file/145638/1/8.PNG
public static Image MakeCircleImage(Image img)
{
Bitmap bmp = new Bitmap(img.Width, img.Height);
using (GraphicsPath gpImg = new GraphicsPath())
{
gpImg.AddEllipse(0, 0, img.Width, img.Height);
using (Graphics grp = Graphics.FromImage(bmp))
{
grp.Clear(Color.White);
grp.SetClip(gpImg);
grp.DrawImage(img, Point.Empty);
}
}
return bmp;
}
void MasterDGVs_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
try
{
if (Master_shanuDGV.Columns[e.ColumnIndex].Name == "StdImage")
{
if (ds.Tables[0].Rows[e.RowIndex]["StdImage"] != "" && ds.Tables[0].Rows[e.RowIndex]["StdImage"] != DBNull.Value)
{
byte[] bits = new byte[0];
bits = (byte[])ds.Tables[0].Rows[e.RowIndex]["StdImage"];
MemoryStream ms = new MemoryStream(bits);
System.Drawing.Image imgSave = System.Drawing.Image.FromStream(ms);
e.Value = MakeCircleImage(imgSave);
}
else
{
System.Drawing.Image imgSave = (Image)DatagridViewCRUD.Properties.Resources.gridUserImage;
e.Value = MakeCircleImage(imgSave);
}
}
}
catch (Exception ex)
{
}
}
5) Search Student Details
In the search button click I will call the bindData() Method to bind the result. We will pass the Student Name as parameter with SP name to our Business Logic Class and from Biz Class we get the result as Dataset and bind the result to DataGridView.
private void btnSearch_Click(object sender, EventArgs e)
{
bindData();
}
private void bindData()
{
try
{
// Bind data to DGV.
SortedDictionary<string, string> sd = new SortedDictionary<string, string>() { };
sd.Add("@StudentName", txtName.Text.Trim());
ds = bizObj.SelectList("USP_Student_Select", sd);
Master_shanuDGV.DataSource = null;
if (ds.Tables[0].Rows.Count > 0)
{ Master_shanuDGV.DataSource = ds.Tables[0];
}
}
catch (Exception ex)
{
}
}
6) Insert/Edit Student Details:
We will create new form for Insert and Update .We use one form for both Add/Edit Student Details. We design our form with all the needed controls and we will add a PictureBox and Upload Button to save the Student Profile photos to SQL Server.
https://code.msdn.microsoft.com/site/view/file/145639/1/2.PNG
From our main form for Add we pass parameter 0 for Add and we pass Student ID as parameter for Edit.** **
Here we can see from our Add Student button Click we will pass the parameter as “0” for Student Add form.
private void btnStaffAdd_Click(object sender, EventArgs e)
{
frmSudentAdd obj = new frmSudentAdd("0");
obj.ShowDialog();
bindData();
}
In frmSudentAdd Form Constructor we will get the Studnets ID passed from Main form and stored in local variable.
public frmSudentAdd(string StudentID)
{
InitializeComponent();
StudentIDS = StudentID;
}
In Form Load we will check if the StudentIDS is not equal to 0 which means it is for Add new Student. IF the StudentIDS is greater than 0 then it is for edit.
private void frmSudentAdd_Load(object sender, EventArgs e)
{
try
{
isImageCaptuerd = false;
// setFont();
if (StudentIDS != "0")
{
displayVisitorDetails();
}
}
catch (Exception ex)
{
}
}
If the Student ID is passed for the Edit then The Student ID will be passed as parameter to get the details of the Student and display the details for edit.
private void displayVisitorDetails()
{
// lblUserType.Text = VisitorTypes;
try
{
SortedDictionary<string, string> sd = new SortedDictionary<string, string>() { };
//sd.Add("@searchType", VisitorTypes);
sd.Add("@std_ID", StudentIDS);
DataSet ds = new DataSet();
ds = bizObj.SelectList("USP_StudentID_Select", sd);
if (ds.Tables[0].Rows.Count > 0)
{
txtStudentID.Text = ds.Tables[0].Rows[0]["StdNO"].ToString();
txtstdName.Text = ds.Tables[0].Rows[0]["StdName"].ToString();
txtEmail.Text = ds.Tables[0].Rows[0]["Email"].ToString();
txtphone.Text = ds.Tables[0].Rows[0]["Phone"].ToString();
txtAddress.Text = ds.Tables[0].Rows[0]["Address"].ToString();
if (ds.Tables[0].Rows[0]["StdImage"].ToString() != "")
{
byte[] bits = new byte[0];
bits = (byte[])ds.Tables[0].Rows[0]["StdImage"];
MemoryStream ms = new MemoryStream(bits); this.picImage.Image = System.Drawing.Bitmap.FromStream(ms);
ms = null;
}
}
}
catch (Exception ex)
{
}
}
**Upload Image: **In upload Image Button click select the image file using OpenFileDialog and add the selected image to the PictuerBox.
private void btnCaptuer_Click(object sender, EventArgs e)
{
try
{
isImageCaptuerd = false;
OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = "JPEG Files (*.jpeg)|*.jpeg|PNG Files (*.png)|*.png|JPG Files (*.jpg)|*.jpg|GIF Files (*.gif)|*.gif";
ofd.Title = "Please Upload Image";
if (ofd.ShowDialog() == DialogResult.OK)
{
isImageCaptuerd = true;
picImage.Image = Image.FromFile(ofd.FileName);
}
}
catch (Exception ex)
{
}
}
https://code.msdn.microsoft.com/site/view/file/145640/1/3.PNG
Save Button Click
In Save Button click first we check for New User or Edit the existing user. For New user call the
private void btnSave_Click(object sender, EventArgs e)
{
if (StudentIDS != "0")
{
EditStaffDetails();
}
else
{
AddNewStaffDetails();
}
}
Add New Student:
We will pass all the parameter to the BIZ class with Image as Byte Object. After Successful insert we will display the message to the user.
private void AddNewStaffDetails()
{
try
{
byte[] ImageData = null;
string result = "";
if (isImageCaptuerd == true)
{
try
{
if (picImage.Image != null)
{
ImageData = imgToByteArray(picImage.Image);
}
}
catch (Exception ex)
{
}
}
SortedDictionary<string, string> sd = new SortedDictionary<string, string>() { };
DataSet ds = new DataSet();
ds = bizObj.SP_student_ImageInsert("USP_Student_Insert", txtstdName.Text.Trim(),
txtEmail.Text.Trim(),
txtphone.Text.Trim(),
txtAddress.Text.Trim(),
ImageData);
if (ds.Tables[0].Rows.Count > 0)
{
result = ds.Tables[0].Rows[0][0].ToString();
if (result == "Inserted")
{
MessageBox.Show("Student Added Successful, Thank You!", "Successfull", MessageBoxButtons.OK, MessageBoxIcon.Information);
this.Close();
}
else
{
MessageBox.Show(result, "Error", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
}
}
catch (Exception ex)
{
}
}
https://code.msdn.microsoft.com/site/view/file/145641/1/4.PNG
Edit Student Details:
For Edit in Main form DataGridView Cell Content Click we will get the selected student id and pass the Id to frmStudentAdd for editing the student details.
private void Master_shanuDGV_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
if (Master_shanuDGV.Columns[e.ColumnIndex].Name == "Edit")
{
try
{
string studentID = ds.Tables[0].Rows[e.RowIndex]["StdNO"].ToString();
frmSudentAdd obj = new frmSudentAdd(studentID);
obj.ShowDialog();
bindData();
}
catch (Exception ex)
{
}
}
We can edit the Student details and also update any new Profile photos for the students. We will pass all the parameter to the BIZ class with Image as Byte Object. After Successful update we will display the message to the user.
private void EditStaffDetails()
{
try
{
byte[] ImageData = null;
string result = "";
if(picImage.Image!=null)
{
try
{
ImageData = imgToByteArray(picImage.Image);
}
catch (Exception ex)
{
}
}
SortedDictionary<string, string> sd = new SortedDictionary<string, string>() { };
DataSet ds = new DataSet();
int StudentID = Convert.ToInt32(StudentIDS);
ds = bizObj.SP_student_ImageEdit("USP_Student_Update", StudentID,txtstdName.Text.Trim(),
txtEmail.Text.Trim(),
txtphone.Text.Trim(),
txtAddress.Text.Trim(),
ImageData);
if (ds.Tables[0].Rows.Count > 0)
{
result = ds.Tables[0].Rows[0][0].ToString();
if (result == "Updated")
{
MessageBox.Show("Student Updated Successful, Thank You!", "Successfull", MessageBoxButtons.OK, MessageBoxIcon.Information);
this.Close();
}
else
{
MessageBox.Show(result, "Error", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
}
}
catch (Exception ex)
{
}
}
// Picbox to Byte Convert
public byte[] imgToByteArray(Image img)
{
using (MemoryStream mStream = new MemoryStream())
{
img.Save(mStream, img.RawFormat);
return mStream.ToArray();
}
}

** 7) Delete Student Details:**
https://code.msdn.microsoft.com/site/view/file/145643/1/6.PNG
In the DataGridView Cell Content click event we will check for the clicked Column is equal to delete. If the Clicked column is delete then we display the confirmation box for user for confirmation to delete. If user confirms for delete then we will delete the selected Student details.
private void Master_shanuDGV_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
if (Master_shanuDGV.Columns[e.ColumnIndex].Name == "Edit")
{
try
{
string studentID = ds.Tables[0].Rows[e.RowIndex]["StdNO"].ToString();
frmSudentAdd obj = new frmSudentAdd(studentID);
obj.ShowDialog();
bindData();
}
catch (Exception ex)
{
}
}
else if (Master_shanuDGV.Columns[e.ColumnIndex].Name == "Delete")
{
try
{
string studentID = ds.Tables[0].Rows[e.RowIndex]["StdNO"].ToString();
if (MessageBox.Show("Are You Sure to Delete Student Details ?", "Delete Student", MessageBoxButtons.YesNo) == DialogResult.Yes)
{
SortedDictionary<string, string> sd = new SortedDictionary<string, string>() { };
sd.Add("@std_ID", studentID);
DataSet ds1 = new DataSet();
ds1 = bizObj.SelectList("USP_Student_Delete", sd);
if (ds1.Tables[0].Rows.Count > 0)
{
string result = ds1.Tables[0].Rows[0][0].ToString();
if (result == "Deleted")
{
MessageBox.Show("Student Deleted Successful, Thank You!", "Successfull", MessageBoxButtons.OK, MessageBoxIcon.Information);
bindData();
}
}
}
}
catch (Exception ex)
{
}
}
}
