C# .NET - How to deselect the first row when the form i loaded in DataGridView in Windows Application?

Hi all,

I am displaying the records in DataGridView in Form Load event in Windows Application.  My problem is after binding all the value it's take the selected index =0 (the first row) even I did not select any row from the DataGridView. After the data is loaded in DataGridView the first is selected automatically and Selected Index =0. 

 I used the "dataGridViewProducts.ClearSelection()" in my load event. But it hides the default selection while the form is loaded but I could not prevent the Selected Index=0.

How to do that?

Thanks

Load Event

 

did you try
DataGridView1.Rows(0).Selected = False

'unselect previously selected row
DataGrid1.UnSelect(DataGrid1.CurrentRowIndex)

To get the first deselected:
DataGridView1.Rows(0).Selected = False

Hi,

It's unselect the first row after binding the value, but still the selectedIndex  is  0 . I want to set the selectedIndex = -1 after the binding is finished in load event.

Any other idea...

Thanks

I think you are doing something else to the DataGridView after the Clear Selection.

Otherwise, clear Selection is for this very purpose.

Hi

I answer this question for another visitors that have same problem.

you can deselect rows in form1.shown event or in datagridview.RowPostPaint event like this:

private void dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
{
   if (e.IsLastVisibleRow)
   dataGridView1.Rows[0].Selected = false;
}

if you refresh datagridview in your program and you want to select last selected rows you can use int variable for save index of before refresh. 

Put this in Form_Paint
DataGridView1.Rows[0].Selected=false
