ToolTip does not work

[Vitaly]

Hi,

I use programmatically columns generation:

var col = new GridViewDataColumn
{
     DataMemberBinding = new Binding(column.Name),

        Header = column.Header,

        ToolTip = new Binding(column.Description)
};
........................

for GridView:

<telerik:RadGridView x:Name="dgvResults" AutoGenerateColumns="False" CanUserDeleteRows="False" SelectionMode="Extended" IsReadOnly="True"
                             ShowGroupPanel="False" CanUserFreezeColumns="False" IsFilteringAllowed="True" RowIndicatorVisibility="Collapsed" ScrollMode="Deferred" EnableRowVirtualization="True" EnableColumnVirtualization="True"
                             ColumnWidth="170">
..............
</telerik:RadGridView>

But I can't see ToolTips for columns.
What is problem?

Thanks!

Hello,

In order to show a ToolTip for every cell of a column, you have to set the TooltTip at cell level. For that purpose you could apply a style targeting GridViewCell.
For example:

<Style TargetType="{x:Type telerik:GridViewCell}">
            <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Mode=Self}, Path=Value, Mode=TwoWay}"/>
</Style>

Please let me know how this works for you.

Kind regards,

Hi Didie,

Thanks for replay. But I need ToolTip for columns in header, not for cell.

Hello,

 You can create a TextBlock, set desired ToolTip for the TextBlock and assign this TextBlock as a column Header.
