Using Ajax control in User Control (ascx) [modified]
-
Tach experts .. I have ne problem where I do not know to solve that... I have a control that is added in a page. Basically it is a Content Management System. It selects a new page and can add different controls. In the control itself, I use a ModalPopupvon Ajax, but who needs a script manager. Now I wonder whether in the side where the control is already added a ScriptManager exists otherwise I add one. Here
void AddScriptMagnager()
{
//get the existing ScriptManager if it exists on the pageScriptManager \_scriptMan = ScriptManager.GetCurrent(this.Page); if (\_scriptMan == null) { //create new ScriptManager and EnablePartialRendering or whatever \_scriptMan = new ScriptManager(); \_scriptMan.EnablePartialRendering = true; \_scriptMan.EnableScriptLocalization = true; if (this.MuMPage.Page.Form != null) { foreach (Control ctrl in this.MuMPage.Page.Form.Controls) { this.MuMPage.Page.Controls.Add(\_scriptMan); } } } }I always get the error that a Extendersteuerelemente may not be registered before PreRender. I appreciate any help and thanks a lot in advance.

[CODE] There is a defined tag for this, <pre> implemented by clicking the "code block" toolbar item directly above this textarea. Please correct your post and read the posting guidelines for this site.

Add where are you calling the AddScriptManager method? Obviously no in the PreRender event handler. The common implementation is to include a ScriptManger in the master page so it is not necessary to be included in child pages and is available for use.

You wrote the master page correct? Add a ScriptManager! If you did not write the master page then the author probably did not intend for Ajax to be used in this manner

Nope, i c´ant! This is Standart site for everysite inour CMS. I'm trying to do exactly that! Just when none is there in the page where I try to add the control at runtime and add a Script Manager. And i get Collection was modified; enumeration operation may not execute.
