如何从XAML中为样式指定控件的工具提示？ [英] How to specify a ToolTip for a control in a Style from XAML?

问题描述

我正在使用Microsoft CodePlex项目的WPF数据网格。我有一个自定义控件，我想要数据绑定到datagrid行的一个字段。我无法为我的生活找出如何在datagrid行上指定一个工具提示。

我最接近的是使用一个带有Setter的RowStyle来设置工具提示，但这只适用于文本。当我尝试将ControlTempalte作为ToolTip的值，它显示在ControlTemplate类型上调用ToString的结果。

我想我需要设置ToolTip的Template属性，但是我似乎无法弄清楚如何做到这一点...

 < dg：DataGrid Name =dgResultsAutoGenerateColumns =True> 
 
< dg：DataGrid.RowStyle> 
 
 
< Style TargetType ={x：Type dg：DataGridRow}> 
 
< Setter Property =ToolTip> 
< Setter.Value> 
 
< ControlTemplate TargetType ={x：Type ToolTip}> 
< StackPanel> 
< TextBlock> txt1< / TextBlock>< TextBlock> txt2< / TextBlock> 
< / StackPanel> 
< / ControlTemplate> 
 
 
< /Setter.Value> 
< / Setter> 
< / Style> 
 
< / dg：DataGrid.RowStyle> 
 
< / dg：DataGrid> 
  

解决方案

...

由于某种原因，我无法直接使用Value.Setter设置值。如果我将工具提示的内容定义为静态资源，然后将其设置在DataGrid.RowStyle的Style属性中。

所以，datagrid行样式如下所示：

 < Style TargetType ={x：Type dg：DataGridRow}> 
 
< Setter Property =ToolTipValue ={StaticResource resKWIC}> 
< / Setter> 
< / Style> 
 
< / dg：DataGrid.RowStyle> 
  

资源是

 < Window.Resources> 
< StackPanel x：Key =resKWIC> 
< TextBlock> f1< / TextBlock> 
< TextBlock> f2>< / TextBlock> 
< / StackPanel> 
< /Window.Resources> 
  

谢谢！

I'm using a the WPF datagrid from the Microsoft CodePlex project. I have a custom control that I want to databind to a field from the row of the datagrid. I can't for the life of me figure out how to specify a tooltip on a datagrid row.

The closest I've come is to use a RowStyle with a Setter to set the tooltip, but this only seems to work for text. When I try to put a ControlTempalte in as the Value for the ToolTip, it displays the result of calling ToString on the ControlTemplate type.

I think I need to set the "Template" property of the ToolTip, but I can't seem to figure out how to do that...

  <dg:DataGrid Name="dgResults" AutoGenerateColumns="True">

            <dg:DataGrid.RowStyle >


            <Style TargetType="{x:Type dg:DataGridRow}">

                <Setter Property="ToolTip"  >
                    <Setter.Value>

                        <ControlTemplate TargetType="{x:Type ToolTip}">
                           <StackPanel>
                                 <TextBlock>txt1</TextBlock><TextBlock>txt2</TextBlock>
                           </StackPanel>
                        </ControlTemplate>


                    </Setter.Value>
                </Setter>
            </Style>

        </dg:DataGrid.RowStyle>

  </dg:DataGrid>

解决方案

Figured it out... took me about 6 hours...

For some reason, I can't set the value directly using Value.Setter. If I define the content for the tooltip as a static resource though, and then set it in the Style property of the DataGrid.RowStyle it works.

So, the datagrid row style looks like:

            <Style TargetType="{x:Type dg:DataGridRow}">

                <Setter Property="ToolTip" Value="{StaticResource resKWIC}">
                </Setter>                 
            </Style>

        </dg:DataGrid.RowStyle>

And the resource is

<Window.Resources>
    <StackPanel x:Key="resKWIC">
        <TextBlock>f1</TextBlock>
        <TextBlock>f2></TextBlock>
    </StackPanel>
</Window.Resources>

Thanks!
