Tooltip when text exceeds column width

[Ronald]

Hi,

I received a request from a customer about showing tooltips on cells when the cell contents exceeds the size of the cell.
Our windows forms client has that functionality using ms listview control. (See attached image.)

In my Silverlight application I display a thumbnail of the document when hoovering over the first column, so I thought I could set the tooltip in the same section: GridViewCell.MouseEnter.

In the MouseEnter handler I measure the width of the column and a temporary Textbox with the contents of the column. If it exceeded I set the tooltip. (Expecting some problems with datetime columns etc.)

var tb = new TextBlock { Text = cell.Value.ToString() };
if (tb.ActualWidth > cell.ActualWidth)
{
 cell.SetValue(ToolTipService.ToolTipProperty, tb.Text);
 return;
}
cell.SetValue(ToolTipService.ToolTipProperty, null);

And the result: No tooltip gets displayed, is there a way to accomplish this?

Kind regards,
Ronald

Hello Ronald,

As it turns out, you can not achieve this functionality with the current implementation of RadGridView.

Please excuse us for the inconvenience caused!

Hi,

I'm using a popup control instead of the tooltipservice.
And the customer is happy with this solution, so I'm also happy!

Perhaps you can add this functionality in future releases of your nice products.

Best regards,
Ronald
