Terelik PostBack Lost All data and do any action.

[Jorge]

Hi guys!

I have the following scenario .
[
I use RadControls for ASP.NET AJAX Q1 2012
Visual Studio 2010
C# & Asp
 ]

1 Aspx
5 User Controls
    UserControlCatalogo
    UserControlDetalle
    UserControlDetalleInterno1
    UserControlDetalleInterno2
    UserControlDetalleInterno3

The aspx page contains a call to " UserControlCatalogo " contains a RadGrid with this data, choose "edit " or "new " in this open RadGrid PopUp containing at UserControlDetalle .

The UserControlDetalle contains a set of RadTextBox and RadTabStrip ( tab panel ) which contains three tabs .

Tab 1 -> contains UserControlDetalleInterno1
Tab 2 -> contains UserControlDetalleInterno2
Tab 3 -> contains UserControlDetalleInterno3

UserControlDetalleInterno1 contains another RadGrid you want to do the following : By clicking on "new" or "edit " expands to display fields and add new data.

The problem is that when I use the "edit" or "new" function from radgrid, the template is not opened to fill data only "flashes" the popup and the table does nothing * in debuging enters the post back , refresh bd updates, the radgrid  datasourse * ... and ends ... * if I remove "ObtenerDatos", the table does not appear *

i cant add or edit my radgrid items :C

Hi Jorge,

I noticed that you have use a simple data binding in your grid with the automatic CRUD operation which is not supported scenario. In order to use an automatic Insert/Update/Delete operation you have to use the advanced data binding. The aforementioned data binding topics elaborate more on the difference between the two methods and how to implement them into your project.

Hi Jorge,

As far as I can see your code looks correct. Could you please provide a small runnable sample in order to observe the issue further? Meanwhile I would recommend you to examine the following live demo which demonstrates how to implement an edit form template.
