[Solved] RadGridView Multiple Selection - CurrentRow Remains Highlighted After Being Deselected

[Shiori]

Product Information

• Product: Telerik UI for WinForms
• Control: RadGridView
• Version: 2025 Q4

Desired Behavior

When multiple rows are selected, I would like to deselect only the clicked row if the user clicks a row that is already selected.

Current Implementation

I implemented the following logic in the event:CurrentRowChanging

void Grid_CurrentRowChanging(object sender, CurrentRowChangingEventArgs e)

{

　if (e.CurrentRow != null && e.NewRow != null)

　{

　　if (e.CurrentRow.IsSelected && e.NewRow.IsSelected)

　　{

　　　e.Cancel = true;

　　　e.NewRow.IsSelected = false;

　　}

　}

}

Behavior Observed

Case 1

Initial state:

• Row A, Row B, and Row C are selected.
• CurrentRow = Row A.

Action:

• Click Row B.

Result:

• Row B is deselected.
• CurrentRow remains Row A.
• The visual state is updated correctly and Row B is no longer highlighted.

This works as expected.

Case 2

Initial state:

• Row A, Row B, and Row C are selected.
• CurrentRow = Row A.

Action:

• Click Row A (the CurrentRow itself).

Result:

• Row A is removed from the selection.
• The row is no longer contained in .SelectedRows
• However, the entire row remains highlighted in blue.

Investigation Results

I confirmed that is not fired when the user clicks the CurrentRow itself, since the current row is not changing.CurrentRowChanging

After clicking the CurrentRow, I checked the following properties:

row.IsSelected == false

rowElement.IsSelected == false

row.IsCurrent == true

rowElement.IsCurrent == true

rowElement.ContainsFocus == true

radGridView1.SelectedRows.Contains(row) == false

Therefore, the row appears to be completely deselected internally.

Additional Tests

I tried forcing UI updates using the following methods, but the visual appearance did not change:

radGridView1.TableElement.Update(GridUINotifyAction.StateChanged);

radGridView1.TableElement.Invalidate();

radGridView1.Refresh();

 

Question

Although the row is no longer selected:

row.IsSelected == false

radGridView1.SelectedRows.Contains(row) == false

the entire row remains highlighted in blue.

Is this expected behavior caused by the CurrentRow/Focus visual state, or could this be a rendering issue?

Additionally, is there a recommended way to achieve the following behavior?

• Keep the CurrentRow unchanged.
• Preserve the remaining selected rows.
• When the CurrentRow is clicked again, remove its visual selection highlight so that it appears deselected.

Any guidance or recommended approach would be greatly appreciated.

Thank you.

The issue looks like it can be resolved with the following code:

 private void GridView_RowFormatting(object sender, RowFormattingEventArgs e)
 {
     if (e.RowElement.RowInfo.IsSelected)
     {
         e.RowElement.DrawFill = true;   
         e.RowElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;  
         e.RowElement.DrawBorder = true;
         e.RowElement.BorderBoxStyle = Telerik.WinControls.BorderBoxStyle.SingleBorder; 
     }
     else
     {
         e.RowElement.DrawFill = false;
         e.RowElement.DrawBorder = false;
     }
 }

 private void GridView_CellFormatting(object sender, CellFormattingEventArgs e)
 {
     if (e.CellElement.RowInfo.IsSelected)
     {
         e.CellElement.DrawFill = true;
     }
     else
     {
         e.CellElement.DrawFill = false;
     }
 }

However, the ">" indicator for the CurrentRow and the border that remains around the selected cell are still displayed.

Is there a way to remove these as well?

Hi, Shiori,

Thank you for contacting us.

To remove the border over the selected cells, you can use DrawBorder=false in the CellFormatting event:

private void GridView_CellFormatting(object sender, CellFormattingEventArgs e)
{
    if (e.CellElement.RowInfo.IsSelected)
    {
        e.CellElement.DrawFill = true;
       e.CellElement.DrawBorder = false;
    }
}

If you want to remove the selected row indicator ('>'), you can use this:

this.radGridView1.MasterTemplate.ShowRowHeaderColumn = false;
