我已正确绑定Telerik RadGridView,第一列是绑定复选框:
<telerik:GridViewCheckBoxColumn DataMemberBinding="{Binding Selected, Mode=TwoWay}"
Header="Generate" Width="95" IsReadOnly="False"/>
Run Code Online (Sandbox Code Playgroud)
我可以点击并更改复选框状态没问题.问题是选中复选框并不直观.为了让用户单击复选框,他们必须先单击复选框单元格,再次单击以激活,然后再次单击以选中复选框.单击三次以选中复选框.
有没有更好的或本地的方式使这无缝?我希望用户能够单击一个复选框并立即查看它,无论是否已选择行/单元格.我希望用户只需点击一下即可进行检查.
Infragistics控制可以在几年前完成.
有人可以解释如何在Telerik RadGridView for Silverlight中获得更直观的复选框行为吗?
