Row Double Click

[Kevin Meyer]

Is there a way to differential data row double-clicks from double-clicks in the header or scroll bar.  RadGridView::DoubleClick seems to fire when anything is double clicked, and the sender is always the grid, not the specific element.

Looking at MouseDoubleClick, I think I might be able to use the event's X and Y to get the child control at that position and check to see if it's a data row.  Are there other options?

Hello Kevin,

Thank you for this question.

I would suggest using the CellDoubleClick event. This event is fired only when a cell element is hovered. To use the event effectively you should set the grid to read only mode by setting the ReadOnly property to true. When processing the CellDoubleClick event, you can get the current cell through the CurrentCell property of RadGridView. Consider the code below:

void radGridView1_CellDoubleClick(object sender, GridViewCellEventArgs e)
{
    object value = this.radGridView1.CurrentCell.Value;
}

You can get the element that is currently hovered by using the GetElementAtPoint method. Take a look at the following code snippet:

void radGridView1_DoubleClick(object sender, EventArgs e)
{
    Point pt = this.radGridView1.PointToClient(Control.MousePosition);
    GridCellElement cell =  this.radGridView1.ElementTree.GetElementAtPoint(pt) as GridCellElement;
    if (cell != null)
    {
        //...
    }
}

I hope this helps. Please contact me if you need further assistance.

To act only on double clicks on data rows, I use the following code in the CellDoubleClick handler:

// make sure we do have a valid current row
if(_grid.CurrentRow==null)
{
    return;
}

// make sure we have a data row
if(_grid.CurrentRow.RowElementType!=typeof(GridDataRowElement)
{
    return;
}

// process the event from here on

Hi erwin,

You are correct, thank you for the additional info. Another way of doing this is to check if the CurrentRow is an instance of GridViewDataRowInfo.

Thanks, this did help me:
The code below determines whether the current row is a data row (and whether the double click event should be processed).

Private Sub RadGrid1_CellDoubleClick(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles RadGrid1.CellDoubleClick

   Dim bProcessDoubleClick As Boolean = False

   If RadGrid1.CurrentRow IsNot Nothing Then
      If TryCast(RadGrid1.CurrentRow, GridViewDataRowInfo) IsNot Nothing Then
         bProcessDoubleClick = True
      End If
   End If

   If bProcessDoubleClick Then
      'Logic
   End If

End Sub
