DropDownList selected item is not correct in updating

I have a DetailsView1 tied to SqlDataSource3.  There is a DropDownList, dlPlant, in a template in one of the rows in edit mode.  When the user clicks the Update link, I try to catch the selected value of dlPlant in SqlDataSource3_Updating.  However, I find that the selected value in SqlDataSource3_Updating is not the value the user has selected while in edit mode, but always the intial value at the time the DetailsView1 was entering the edit mode.  Why is this so?

My code is as follows:

protected void SqlDataSource3_Updating(object sender, SqlDataSourceCommandEventArgs e)
DropDownList dl;
Page.Title = dl.SelectedValue;

 Is this the right method to find out the selected value of a DropDownList in edit mode?

can you check if the drodownlist's autopostback property is to "true"?

alternatively, you may use the dropdownlist's SelectedItem.Value property to determine the value.

as stated above, how is the dropdownlist populated? is it by design time or runtime... are there values bound to the dropdownlist's  item text and item value properties?

AutoPostBack is false.

I checked and SeletedItem.Value is the same as .SelectedValue.

My drop down list is populated inside its Load event handler.  The initial value is also set inside there.  I checked and the Load event was called only once, presumabley when the DetailsView entered the edit mode.

I solved it. The problem goes away if I populate the drop down list in its DataBinding event rather than the Load event.

Changing Selected item of a dropdownlist when posting back from other control
Hi, I have several controls in an asp.net web form, including a dropdownlist. When I do a postback from one of the controls (not the dd list), I want to change the content of the dd list (this goes ok), but I also want to change the selected item in the list. In the code, setting the selected item seems to work (though the debugger I see it sets the selected item correctly), but when I look at the html there is NO ITEM SELECTED in the dd list!! How is this possible?? I'm totally confused. By the way, all actions are happening in the Page_Load. It's probably a viewstate problem or...

When the user selects an item in the DropDownList, I want another DetailsView to advance to the record associated with the selected item so that the user can see more details on the item they are going to order.

When I put it inside the DetailsView I get this error:Exception Details: System.InvalidOperationException: Could not find control 'ddItems' in Cont...
