Hi
In my page am using ajax calendar and other ajax controls. All the pages were developed on visual studio platform and last month we linked all the pages to sharepoint. Till yesterday all the pages were working fine. But all of a sudden, now the pages that are using ajax controls are throwing error.

The control with ID 'CalExTfdate' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

When i checked the code, script manager is present in the aspx page. Any guess where it went wrong for the pages to throw error.

Thanks in advance
Naina

Put your ScriptManager before any other control in your page.
Are you writing your javascript functions in html head tag?
If so, try to move all your javascript code just before where your body tag ends.
Hope this will resolve your problem.

Anurag Gandhi is Right.The ScriptManager should be always appear before the control that you want to use that is Ajax related, usually we put it in the master page so that it can be available for all controls.

There are many ways of doing so.

1. You can populate your drop down something list like this:

foreach(DataRow row in myDataTable.Rows)
{
    string text = row["FirstName"].ToString() + " " + row["LastName"].ToString() + " [" + row["Id"].ToString() + "]";
    DropDownList1.Items.Add(new ListItem(text, row["Id"].ToString()));
}

2. You can use linq projection on the dataTable and use teh linq query result as your DropDownList datasource.

Hope this will help.

You can get firstname by just splitting ddl.SelectedItem.Text Smile | :)

Instead of adding the ID to the listItem value, add the first name as below:

foreach(DataRow row in myDataTable.Rows)
{    
   string text = row["FirstName"].ToString() + " " + row["LastName"].ToString() + " [" + row["Id"].ToString() + "]";    
   DropDownList1.Items.Add(new ListItem(text, row["FirstName"].ToString()));
}

and then retrieve this, rather than the text using:

ddl.SelectedItem.Value

Hi
I have a link button which is part of my user control. Further, the control is actually added to the control dynamically. Whilst, I can see the control, and is added to the page without any visible errors, but when I click on to fire an event which on that user control nothing happens. What is even more odd, if I add a break point to event, and then click in debug mode, I can't even reach the break point!

To try and resolve this, I have tried giving the link button ids, and ensured they unique, added override using OnInit and used the createchildcontrols method, but nothing seems to work!

Has anyone came across and if so, can give me a solution?

Where in the code is the linkbutton created dynamically? Put a breakpoint on page_load and you should see that this is hit when you click the linkbutton. It doesn't fire the event because the control is not recreated again as part of the postback.

Try recreating the control in page_load if isPostBack = true. Remember to recreate your event handler here as well.

Hi
I had already done all of this.

The linkbutton is created on the usercontrol form.

I have added the linkbutton creation to, with this.linkbutton1.click += EventHandler(this.linkbutton1_click); to Page_Load, OnInit, Page_PreRender and CreateChildControls.

The event will not fire even after doing all of this!
