Hi
I developed a usercontrol with a textbox and an htmlInputHidden
When I add my usercontrol in a webform, it works properly
If I add my control in a template column of a datagrid i have some problems
When I load the webform, the usercontrol has a UniqueID like this: "LookUp1:txtRisultato", then I value the text of this textbox with a client-side script. If i post the page, the value saved in the textbox.text is null, but i see that the UniqueID is changed, and now is "DataGrid1:LookUp1:txtRisultato"
How can i refer to my usercontrol with an ID which doesn't changes
Why the UniqueID changes

P.S. I noticed that if I value the textbox sending the right ID (DataGrid1:LookUp1:txtRisultato) the post is made properl

Thank yo

Hi, Alessandro Rossi,

The UniqueID in this case receives its actual (and final) value after the
binding of the DataGrid. I suppose that you are reading it at some point
before that. That is why it has different value.

Hope this helps

No, I found the problem
I built the client-side script when the UniqueID wasn't complete (in the set method of a property). Now I moved the code in a Control PreRender event handler procedure's, and now all works properly

Thank you for the interest

Hi, Alessandro Rossi,

The code in the PreRender method is executed *after* the binding of the
DataGrid. I was supposing (correctly) that you were reading the UniqueID
*before* the binding.

Anyway, it's good that you have resolved your problem.

Greetings
