Help with changing headertext color of DataGridView if value found using VB.NET

Hi,

How do you loop through a DataGrid View and change all columnheaders text color if a value is found (i.e. textboxt.text = BEL) in their cell?

Thanks,

Victor

Hi again,

Is it also possible to set the condition for multiple values (i.e.Textbox.Text = 'BEL', 'USA')

try this , will change header style for all columns.

Protected Sub GridView1_RowDataBound(sender As Object, e As GridViewRowEventArgs)  

   If e.Row.RowType = DataControlRowType.DataRow Then

         If e.Row.Cells(2).Text ='BEL' OR e.Row.Cells(2).Text =''USA''   Then

         GridView1.HeaderStyle.ForeColor = Color.OrangeRed

        End If

     End If

7 End Sub

Pratima code is for a GridView, in a web application.

In a DataGridView, the following will do the trick:

	Sub CheckForValues()

		For row As Integer = 0 To DataGridView1.Rows.Count - 1
			For col As Integer = 0 To DataGridView1.Columns.Count - 1
				If CStr(DataGridView1.Item(col, row).Value) = "BEL" Or CStr(DataGridView1.Item(col, row).Value) = "USA" Then
					DataGridView1.ColumnHeadersDefaultCellStyle.BackColor = Color.Red
					Exit Sub
				End If
			Next
		Next

	End Sub

Hi,

I tried the code below, but all the colomn hearders are affected, how do I only change the colors of the columns which contains the values?

Sub CheckForValues()

		For row As Integer = 0 To DataGridView1.Rows.Count - 1
			For col As Integer = 0 To DataGridView1.Columns.Count - 1
				If CStr(DataGridView1.Item(col, row).Value) = "BEL" Or CStr(DataGridView1.Item(col, row).Value) = "USA" Then
					DataGridView1.ColumnHeadersDefaultCellStyle.BackColor = Color.Red
					Exit Sub
				End If
			Next
		Next

	End Sub

Sorry for the bad line. You just asked how to "change all columnheaders ", so I gave you the code for ALL column heaners.
