  • Reference

Definition

Namespace:
System.Windows.Forms
Assembly:
System.Windows.Forms.dll

Gets the index of a specified DataGridColumnStyle.

public:
 int IndexOf(System::Windows::Forms::DataGridColumnStyle ^ element);
public int IndexOf (System.Windows.Forms.DataGridColumnStyle element);
member this.IndexOf : System.Windows.Forms.DataGridColumnStyle -> int
Public Function IndexOf (element As DataGridColumnStyle) As Integer

Parameters

element
DataGridColumnStyle

The DataGridColumnStyle to find.

Returns

Int32

The zero-based index of the DataGridColumnStyle within the GridColumnStylesCollection or -1 if no corresponding DataGridColumnStyle exists.

Examples

The following code example uses the Contains method to determine if a given DataGridColumnStyle exists in a GridColumnStylesCollection. If so, the IndexOf method returns the index of the DataGridColumnStyle, and the Remove method is invoked with the index to remove the element from the collection.

Private Sub RemoveCol(ByVal dc As DataColumn) 
    Dim myGridColumns As GridColumnStylesCollection
    myGridColumns = DataGrid1.TableStyles(0).GridColumnStyles

    If myGridColumns.Contains("FirstName") Then
        Dim i As Integer
        i = myGridColumns.IndexOf(myGridColumns("FirstName"))
        myGridColumns.RemoveAt(i)
    End If
End Sub

Remarks

Use the Contains method to determine if a specific DataGridColumnStyle exists. If so, and you need the index of the element within the collection, use the IndexOf method.
