dropdownlist postback not firing

Hi,

Wierd problem.

Using ASP.NET 2.0.

Have a DropDownList
- <asp:DropDownLi st ID="DropDownLis tMake" runat="server"
CssClass="selec tComparison" AutoPostBack="T rue"
OnSelectedIndex Changed="DropDo wnListMake_Sele ctedIndexChange d" />

Have the corresponding codebehind event handler
- protected void DropDownListMak e_SelectedIndex Changed(object sender,
EventArgs e)
{
if (!DropDownListM ake.SelectedInd ex.Equals("-1"))

this.ChangeMake (Int32.Parse(Dr opDownListMake. SelectedValue)) ;
}

But when I select an item from the dropdownlist the page just
refreshes and no event fires.

When I debug the code on my Page_Load (C#) the if (!this.IsPostBa ck)
returns false i.e. it's not catching the postback. And the event for
the dropdownlist Selected Index Change isn't firing.

ViewState is enabled.

Does anyonw have any ideas??

Hi, I have an issue with the OnSelectedIndexChanged event not firing for a DropDownList control which is in the ItemTemplate of a DataList. I have made an exact copy of the DropDownList control, and placed it outside of the DataList and it fires the event just fine. So it's definitely to do with it being in a template. I've managed to reproduce the issue on a small test app, the code and html is below:

I have two dropdownlists that are bound to the same datasource and I have a couple of questions: 1) Because they are bound to the same datasource, I am assuming that they only make 1 round trip to the DB server -- is that correct? 2) On a user's click of a button, one of the actions in the button OnClick event is to set the selectedindex of the 2nd DDL to that of the 1st. I get a runtime error here that says that the given index is...

The problem I am having is with the SelectedIndexChanged event not always firing or the SelectedIndex property not being correct when the event does fire. The code is below, but here are some details first. The DropDownList is actually a custom control called DropDownListWithCommandEvent that inherits from DropDownList. The reason I have created this is to create a DropDownList that will bubble a Command event to the containing...

Hi guys, I'm trying to learn ASP.NET and got a problem with DroDownList... SelectedIndexChanged doesn't fire. Maybe you'll be able to suggest something. I think it may be connected with the fact I fill this list dynamically. I use the following code:

I have a (.Net 1.1) form with a Repeater and a DropDownList in the ItemTemplate. I programmatically make the DDL Autopostback = true at runtime based on the bound data. That works - I can see the postback happen appropriately. The DropDownList looks like this: <asp:DropDownList id="ddMultiQty" OnSelectedIndexChanged="ddMultiQty_SelectedIndexChanged" runat="server"></asp:DropDownList>

Hi there, I have a web form with some DropDownList controls that I am trying to trap the selection change and run the attached server code. However, even thought the controls have the runat property set to server, the event code does not get executed. Anyone have any ideas?

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
