asp:ListView doesn't leave edit mode when updated

I am using a listView inside an update panel.
The OnItemUpdating event, which is handled in ModulesList_ItemUpdating() is as follows:

C#

protected void ModulesList_ItemUpdating(Object sender, ListViewUpdateEventArgs e)
        {
           //add data into the database
           ModulesList.EditIndex = -1;
           ModulesList.DataBind();
        }

The edited data is being added to database, but ListView remains in edit mode.
The same lines, when added in onItemCancelling event, works perfectly.

C#

protected void ModulesList_ItemCancelling(object sender, ListViewCancelEventArgs e)
     {
         ModulesList.EditIndex = -1;
         ModulesList.DataBind();
     }

I inserted breakpoints for debugging in the onItemUpdated event, the editIndex=-1 is executing but not reflected in the web page.

What am I missing? I have been trying for more than a day :-/

It works if I remove update panel, but i need to use update panel to prevent full page refresh :-/

Solution 1

Probably EditIndex[^] value is -1 (which indicates that no item is being edited) and that's why you can't set it.
Try to add try... catch[^] block to catch errors, especially ArgumentOutOfRangeException[^] exception.

C#

protected void ModulesList_ItemCancelling(object sender, ListViewCancelEventArgs e)
     {
         try
         {
         ModulesList.EditIndex = -1;
         ModulesList.DataBind();
         }
         catch (ArgumentOutOfRangeException ex)
         {
         //show error message         
         }
         catch (Exception ex)
         {
         //show error message
         }
     }

To switch from edit mode to display mode, EditIndex needs to be set to -1. Reference: http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.listview.editindex.aspx

Figured it out . I hadn't included

C#

e.cancel=true;

at the end of ItemUpdating event handler. Now it works perfectly inside update panel. The modified function is:

C#

protected void ModulesList_ItemUpdating(Object sender, ListViewUpdateEventArgs e)
        {
           //add data into the database
           ModulesList.EditIndex = -1;
           ModulesList.DataBind();
           e.cancel=true;
        }
