[Solved] Radgrid does not open Edit and Insert Mode

[Alper Cem]

Hi, I have an issue with radgrid. I have Lİstview and radgrid inside listview. I can not run edit mode and Add new record in radgrid. I followed this example  http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/form-template-update/defaultcs.aspx.

If i add this insert and edit is opening by default but when i press add new record it does not open.

Hi Alper,

In the provided code there is RadGrid defined in the markup and in the code-behind you are creating different RadGrid object which should not be done.

Also the data source for the grid should not be set in the ItemDataBound handler for the RadListView control. The recommended approach is to set RadGrid's DataSource property only in NeedDataSource as it is called automatically. If you need to rebind RadGrid the Rebind() method should be called. If you would like additional information on using NeedDataSource event it is available in this topic.

Additionally when adding Ajax settings programmatically a page lifecycle event should be used as suggested in this article. This needs to be done to ensure that the settings will be added properly when the page is loaded.
