DataGrid：如何将单击处理程序添加到动态图像列 [英] DataGrid: how to add click handler to dynamic image column

问题描述

图像列在运行时添加到DataGrid。

DataGridTemplateColumn templateCol = new DataGridTemplateColumn（）;

templateCol.CellTemplate = XamlReader .Load（string.Format（@"< DataTemplate

xmlns ='http：//schemas.microsoft.com/client/2007'

xmlns：x ='http ：//schemas.microsoft.com/winfx/2006/xaml'

>

< Button BorderThickness ='0'>

< Image Source ='{{Binding {0}，Converter = {{StaticResource myImageConverter}} }}'/>

< / Button>

< / DataTemplate> ;"，

" byteAColumn"

））作为DataTemplate;

Columns.Add（templateCol）;

如果用户点击图片，如何调用代码？

我试图在运行时使用

$ b $添加点击处理程序b

按钮按钮=新按钮（）;

button.ContentTemplate = XamlReader.Load（string.Format（@"< DataTemplate

xmlns ='http：/ /schemas.microsoft.com/client/ 2007'

xmlns：x ='http：//schemas.microsoft.com/winfx/2006/xaml'

>

< Image Source ='{{Binding {0}，Converter = {{StaticResource myImageConverter}}  } /'>

< / DataTemplate>"，

" byteAColumn"

））作为DataTemplate;

Columns.Add（按钮）;

但最后一行出现编译错误

参数1：无法从'系统转换。 Windows.Controls.Button'到'System.Windows.Controls.DataGridColumn' 

是否可以使用它或创建子类按钮或任何其他想法？

解决方案

您可以使用
LoadContent 方法帮助。

Image column is added to DataGrid at runtime.

DataGridTemplateColumn templateCol = new DataGridTemplateColumn();

templateCol.CellTemplate = XamlReader.Load(string.Format(@"<DataTemplate
xmlns='http://schemas.microsoft.com/client/2007'
xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'
>
<Button BorderThickness='0'>
<Image Source='{{Binding {0}, Converter={{StaticResource myImageConverter}}  }}'/>
</Button>
</DataTemplate>",
"byteAColumn"
)) as DataTemplate;

Columns.Add(templateCol);

How to invoke code if user clicks in image ?

I tried to add click handler at runtime using

Button button = new Button();
button.ContentTemplate = XamlReader.Load(string.Format(@"<DataTemplate
xmlns='http://schemas.microsoft.com/client/2007'
xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'
>
<Image Source='{{Binding {0}, Converter={{StaticResource myImageConverter}}  }}'/>
</DataTemplate>",
"byteAColumn"
)) as DataTemplate;

Columns.Add(button);

but got compile error in last line

Argument 1: cannot convert from 'System.Windows.Controls.Button' to 'System.Windows.Controls.DataGridColumn' 

Is is possible to use this or create subclassed button or any other idea ?

解决方案

You can get controls inside DataTamplate with LoadContent method help.
