RadGrid — Not able to edit all rows except last row

问题

I am able to edit (double click) only the last row in a RadGrid. When I select any other row it throws an error.

There was a problem extracting DataKeyValues from the DataSource. Please ensure that DataKeyNames are specified correctly and all fields specified exist in the DataSource.

Has anyone faced this problem? If I'm able to edit one row why not others?

回答1:

You have to declare the dataKeyNames in your MasterTableView .
For Example , if your table has three columns(Column1,Column2,Column3)

<telerik:RadGrid ID="RadGrid1" runat="server">
  <MasterTableView DataKeyNames="Column1,Column2,Column3">  
  </MasterTableView>
</telerik:RadGrid>
