[Solved] Retain values for InsertMode on popup form

[Aaron Hanusa]

I am having an issue retaining the values in a popup form if the save of the underlying object is not successful.  Specifically, I am using a custom ObjectDataSource and handling its Inserting event.  I then attempt to create a new object, bind it's value to those found on the popup's controls, and save the object in a try/catch block.

If the save throws an exception, I set a class level variable (_errorOccurred) to true.  Then, I handle the Grid's ItemUpdated event as shown below:

 

 

protected void RadGrid1_ItemUpdated(object source, Telerik.Web.UI.GridUpdatedEventArgs e)
{
   e.KeepInEditMode = _errorOccurred;
}

What this does is keeps the popup open, which works great.  However, all of the values are lost, and the user has to re-enter all of the values.

How do I retain the values in the popup in this case?

Thanks!

Hi Aaron,

Indeed, in this case, the values will be lost. The reason for this is that the control is rebound. There is no automatic way to preserve the values in the control. To handle this setup, you need to preserve the values entered by the user, and when the control retained in edit mode, you need to restore the values.
I hope this is a suitable approach for you.

Best wishes,
