Model Popup showing as blank when click view button in gridview C#

BeUnique 2,212

I am using ASP.NET application and i used Gridview to show the PDF file.

when i click the view button in the gridview, the file will be opening is perfect.

I am using some search button outside the gridview for filter records in gridview.

Whenever i am using search filter, the gridview has filtered, but, when i click the view button, popup will be displaying as blank at very first time or the previous file will be displaying.

What could be the problem and how to solve this.

below is my code.

The code shown in your quetion is incomplete. Please show minimum but complete sample code required to reproduce your issue.

Hi @SurferOnWww ,

I'm updating my complete code...pls. check.

pls. let me know if you need any more details.

The problem is, After clicking the search button, the record will be filtering in gridview.

when i click the view file, the very first time, the record will be opening as blank or previous record will be showing...

???

Hi @BeUnique,I tested your code and found many problems. The code does not run. The front-end code you provided is very confusing. There are many wavy lines when pasted into VS.

Maybe you can provide a minimal example that can reproduce the problem.

You mentioned that filtering does not work, but you did not provide the relevant code for drpEmployee. It would be better if you also provide your StoredProcedure so that we can test your problem.

Hi @Lan Huang-MSFT ,

Sorry for not giving the proper code.

I have updated the latest code both design and code behind file.

pls. find the table and related scripts

Note : I have used gridview header freeze option. (this is also not working)

CREATE PROCEDURE [dbo].[Spd_EmpDetails_Master](
@Spd_Type Varchar(100)=Null,   
 
@Spd_EmpNo Varchar(100)=null, 
@Spd_EmpName Varchar(200)=null, 
@Spd_FileName Varchar(200)=null, 
@Spd_FilePath varchar(Max)=null 

)
AS
BEGIN
Set NoCount On 

IF @Spd_Type='GET_EmpList'      
	Begin  
		 Select  EmpId,EmpName
		 from Test_EmpDetails A order by EmpName
	End 

IF @Spd_TYPE='GetEmpAccDetails'   
Begin 
		Begin
			select Id,EmpId,EmpName,FileName,FilePath from Test_EmpDetails
		End 
	
End

IF @Spd_TYPE='Search_EmpDetails'   
Begin 
		Begin
			select Id,EmpId,EmpName,FileName,FilePath from Test_EmpDetails where EmpId=@Spd_EmpNo
		End 
	
End


END

GO

CREATE TABLE [dbo].[Test_EmpDetails](
	[Id] [int] IDENTITY(1,1) NOT NULL,
	[EmpId] [varchar](50) NULL,
	[EmpName] [varchar](50) NULL,
	[FileName] [varchar](50) NULL,
	[FilePath] [varchar](max) NULL,
 CONSTRAINT [PK_Test_EmpDetails] PRIMARY KEY CLUSTERED 
(
	[Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, OPTIMIZE_FOR_SEQUENTIAL_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

Hi @BeUnique,

Can you provide the "dbConn" class?

BeUnique 2,212

Hi @Lan Huang-MSFT

pls. find below "dbConn" class file.

DBConnection.cs
****************

using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.SqlClient;
using System.Text;
using System.Data;
using Microsoft.VisualBasic;

{
   public class DBConnection
    {
       private SqlConnection sqlCon;
       public SqlCommand sqlCmd = new SqlCommand();
        private void InitializeCommand(CommandType cmdType, string cmdText)
        {
          sqlCmd.CommandType = cmdType;
          sqlCmd.CommandText = cmdText;
        }
       private void OpenCon(string Sqlstring)
       {
         sqlCon = new SqlConnection(Sqlstring);
         sqlCmd.Connection = sqlCon;
         sqlCon.Open();
       }
       private void DisposeCon()
       {
         if ((sqlCon.State != ConnectionState.Closed))
         {
           sqlCon.Dispose();
           sqlCmd.Dispose();
         }
       }
       public DataSet XcuteResult(string Sqlstring, CommandType cmdType, string cmdText)
       {
         this.InitializeCommand(cmdType, cmdText);
         this.OpenCon(Sqlstring);
         SqlDataAdapter da = new SqlDataAdapter(cmdText, Sqlstring);
         DataSet ds = new DataSet();
         da.SelectCommand = sqlCmd;
         da.Fill(ds);
         if ((sqlCon.State != ConnectionState.Closed))
          {
           sqlCon.Dispose();
           sqlCmd.Dispose();
          }
         return ds;
        }
   }
}

Hi @Lan Huang-MSFT ,

Thanks for highlighting the exact issue. Opening the modal popup issue is resolved now..

I am facing one more problem in this code.

I used column freeze in gridview. But, column freeze is not working at anyway.

what could be the problem.?
