C# - .net DropDownList Gets Cleared After Postback?

Jul 8, 2010

This has been driving me nuts all day. I've seen this problem crop up here a few times, essentially I have a drop down list that populates a form below when it's changed - basic stuff. On first page load everything is fine, but when the dropdownlist is changed, it's entirely blank after postback and the SelectedIndexChanged event never fires. I believe it all points to a viewstate problem. Here's the code..

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="EditUser.ascx.cs" Inherits="Controls_EditUser" %>
<asp:DropDownList OnSelectedIndexChanged="SelectedIndexChanged" AutoPostBack="true" ID="UsersList" EnableViewState="true"
runat="server" DataTextField="EXTRANET_USER_EMAIL" DataValueField="EXTRANET_USER_ID">

Forms Data Controls :: Dropdownlist Postback Always Select First Item?

Mar 24, 2010

I have 2 dropdownlist controls (ddl1 and ddl2). When I pick an item from ddl1, it will update ddl2. The problem is when I pick an item in ddl2, it always selects the first item in the list. Is it that the ddl2 autopostback causes the first ddl1 to reload and results the ddl2 to be refreshed also? Or I didn't set something correctly?

Forms Data Controls :: DropDownList In DataGrid Selected Value Not Being Saved On Postback

Apr 13, 2010

I have a DataGrid that has a dropdown list in an ItemTemplate. Basically, users select a value from the dropdown for each row of the datagrid. When the page is posted back, the selected index of the dropdown list is always reset to 0, and the items are re-bound.

Does anyone know why this might happend? The dropdown items are hardcoded, so there is no external data binding that happens on post back.

Forms Data Controls :: Change The Values In Dropdownlist In Gridview?

Aug 4, 2010

I got a gridview -CompGrid, having 3 columns - Dept, Employees, Status.

The 'Status' tab need to be edited. So that I put a Dropdownlist as an Itemtemplate and connected the 'DataValueField' as 'Status'.

Now I can edit each row by row only. Some times it needs to update all the employees status in one department.

So that I placed 2 more dropdownlists in outside of gridview.

1. Department List, 2. Status List.

My requirement is this, When I select one department and corresponding status, it should update all the records of that department in the grid.
