I'm having difficulty retaining DropDownList selected item so that it corresponds to the new page that is called when the item is selected.

I have some dynamic listbox code that creates a listbox based on information stored in a database. The database access works fine.

Simple problem here. I’ve not used a CheckBoxList control in an ASP.NET application before (ASP.NET 3.5 in this case), and now I need to. Databinding it to the source to populate the items of the list is easy. However, selecting those items which are already stored in the database; I’m not sure how I can do that with databinding. So the question is, how do I databind the items in the CheckBoxList which reflect the items already selected in the database, in this case in a resolution table between the data items table and the lookup table, so that I get what’s in the res...Setting DropDownList Selected Item from dbase SELECT
I've searched everywhere for the answer to this problem, but I can't seem to find the answer. I'm making an edit page for a user to edit their profile. One of the fields is a DropDownList containing a list of states (the states is populated from a database call to a lookup table). I want to match the state the user has in their profile to the appropriate state in the drop-down, and make that item selected. Unfortunately, I can't find any examples on how to do this. Also, since the drop-down control is within a repeater control (to populate the fields), it makes it even more diffi...When to select items in a dropdownlist control?

I know that, but where exactly is the event handler or method that I will need to put my code in?
So you don't load it programatically. If thats the case, did you try Page_LoadT...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 ...SELECT from SELECT
I remember seeing an example where you can do a select from a nested
select, but I cannot seem to make it work.
So it would be something like this:
select max( name )
select name from customer
select name from vendor
Was I dreaming I saw that?

Just add a normal RequiredFieldValidator but set the InitialValue attribute to the text of the ListItem that you want prevent from being selected. Here is an example: <asp:DropDownList AppendDataBoundItems="True" ID="JobTypeDropDownList" runat="server"
