Tooltip on Column title

[Narendra]

 

 

 

Hi,

I want to define a tooltip that will shown, when mouse is over the title of the column.

Used the below code xaml for tooltip, but it is not showing tooltip.

<telerik:GridViewDataColumn Header="First Name"

 

 

 

DataMemberBinding="{Binding FirstName}" ToolTip="First Name Tooltip" />

I am missing any thing.

Thanks,
-Narendra

Hello Narendra,

Use the following code to add a tooltip to column headers:

<telerik:RadGridView Name="radGridViewHeaderCellTooltip" ItemsSource="{Binding}">
<telerik:RadGridView.Resources>
<Style TargetType ="{x:Type telerik:GridViewHeaderCell}">
<Setter Property="ToolTip" Value="{Binding Content, RelativeSource={RelativeSource Self}}"/>
</Style>
</telerik:RadGridView.Resources>
</telerik:RadGridView>

Kind regards,

Thanks for the response.

Is there any other way like setting property of GridViewColumn?

Hello Narendra,

Generally there is no built-in property that will set the tooltip of the header in this way,you should implement it yourself and  GridViewHeaderCellStyle  is the easiest  way to achieve this result.

I would like the grid to pick up the data annotation description as the tool tip. Is this possible?

My code looks like this:

[

 

Display(Name = Consts.DisplayName.MyColumn,Description="Tooltip goes here")]

Hello Narendra,


Please refer to the following markup, which shows the easiest way to implement a tooltip in GridviewHeaderCell:

<UserControl.Resources>
    <Style x:Key="style1" TargetType="telerik:GridViewHeaderCell">
    <Setter Property="ToolTipService.ToolTip" Value="I am a ToolTip"/>
    </Style>
</UserControl.Resources>
    <Grid x:Name="LayoutRoot" Background="White">
        <telerik:RadGridView x:Name="gridView1" ShowInsertRow="True" AutoGenerateColumns="False">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn Header="ID" HeaderCellStyle="{StaticResource style1}" DataMemberBinding="{Binding ID}"/>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>
    </Grid>

You can create the tooltip either in xaml or in code-behind, you can bind it to the property value of your custom object and feel free to modify the code below in in the way you need.

This xaml does indeed add a tool tip when hovering over a column header.  But, afterwards the column header goes blank.  Any ideas?

...for those following the breadcrumbs, here is a telerik workaround to the column header/tooltip issue:

For those, still looking for solution:

<telerik:RadGridView Name="radGridViewHeaderCellTooltip" ItemsSource="{Binding}">
    <telerik:RadGridView.Resources>
        <!-- you can remove BasedOn if you don't use implicit styles -->
        <Style TargetType ="{x:Type telerik:GridViewHeaderCell}" BasedOn="{StaticResource {x:Type telerik:GridViewHeaderCell}}">
            <Setter Property="ToolTip" Value="{Binding Column.(ToolTipService.ToolTip), RelativeSource={RelativeSource Self}}"/>
        </Style>
    </telerik:RadGridView.Resources>
    <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding Property1}" Header="Property1" ToolTip="Property 1 Tooltip" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding Property2}" Header="Property2" ToolTip="Property 2 Tooltip" />
    </telerik:RadGridView.Columns>
</telerik:RadGridView>

Use the following line instead. This will not make the header blank.

 <Setter Property="ToolTip" Value="{Binding Content.Text, RelativeSource={RelativeSource Self}}"></Setter>
