I have a gridview with checkboxes going down the side for each item. Some are enabled and others are not. At the top of the page is a checkbox which when checked will make all the checkboxes on the side enabled. THis is not working and I have tried 2 variations. What am I doing wrong?

I have created a custom control in ASP.net which includes a DropDownList with AutoPostBack set to true. I have also attached an event SelectedIndexChanged for the control.But I find that the event is not fired. Where as normal asp.net DropDownList with AutoPostBack set to true will fire the event. I am using .net 3.5 version in VS2010.
Here is my code:
ServerControl1.cs
[ToolboxData("<{0}:ServerControl2 runat=server></{0}:ServerControl2>")]
public class ServerControl1 : WebControl
{
protected DropDownList drplist;
protected TextBox tb;
protected override void RenderContents(HtmlTextWriter output)
{
[Code]....
When I select the item in 1st dropdownlist, values are fetched from database and want to display in second dropdownlist... but the autopostback is not working for the 1st dropdownlist..

I have an AJAX enabled ASP.Net 3.5 app in which I have:
A Master PageA Web Content PageA User ControlMore precisely, there's a Placeholder control in the Web Content Page into which one of many User Controls are loaded (one at a time or none at all).
The basic User Control I'm working with has a bunch of Labels and one DropDown ListBox. The latter control is a date selector - ie. June 2010, May 2010, April 2010, etc. When the user changes the date, since AutoPostBack = true for the control, a PostBack occurs. But when this happens, the User Control disappears!
All I want is for a partial postback to occur so that I can use the new date to repopulate the various Label controls. I even put the Placerholder control in its own UpdatePanel but this didn't resolve anything - the User Control still disappeared.
After the implementation of ajax drag and drop, we have observed that which is working fine in IE and Firefox and not in chrome and safari, In Google chrome and Safari when we try to drag a module, the page getting scrolling to the top of the page.

and in the code behind I have the following:

Now, when you select an item from the 1st DropDownList, you go t the right page, but then if you click on the browser back page, and select an item from the 2nd drop down, still the 1st drop down event will be fired and then you land on the Fixtures.aspx page again instead of Results.aspx.
I assume it is not a bug and I am missing something in here. I tried Response.Redirect("~/pageurl.aspx",false) as well but still it cause the same sort of problem .

Iam working on a web based form where I have a DDL to which I have attached a field validator which is not working. It should function in such a way that whenever the DDL is left to blank, it gives user an error. I have introduced that BLANK in the DDL using ListItem as I found that as the easisest way out.
<asp:DropDownList ID="DropDownList4" runat="server"
DataSourceID="AccessDataSource4" DataTextField="myState"
DataValueField="myState" AppendDataBoundItems="true">
<asp:ListItem Selected = "True" Text = "" Value = ""></asp:ListItem>

ErrorMessage="RequiredFieldValidator" Text="Required Field"
InitialValue="None" ControlToValidate="DropDownList4" Display="Dynamic">

I cannot get the Drag and Drop functionality of Web Parts is to work. I have a very simple test page with two WebPartZones. . In the OnInit method of the code behind I put the page in design mode. In the first zone I have a textbox.At runtime the text box renders as a web part. When I hover over the web part header my mouse pointer changes the 'move' pointer, but I cannot drag the item. I do not see it dragging and the part never moved. am using Visual Studio 2010 with IE 8. I have tried IE8 in compatibility mode and regular mode. The results are the same.Here is the markup from my test page:
<form id="form1" runat="server">
<div>
<asp:WebPartManager ID="WebPartManager1" runat="server">

I'm struggling with a web form where I have created one date field and couple of drop down lists. These drop down lists populate themselves from a backend MS ACCESS database file. My problem is that I am not able to make the two drop down menus dependent in a manner that when the first drop down menu is selected the second should be populated accordingly?

I am using Visual Studio 2008 and created a simple ASPX page with two drop downs in it. I am using the Update Panel so that when any item is seleted in drop down 1 the second drop down selected item will change accordingly.

see the code below I am using.

View 6 RepliesI have two DropDownLists inside an UpdatePanel.
The values shown inside the second are dependent of the selectedValue on the first, so, I need AutoPostBack=true.
But, whenever the selected value in the first DropDownList is changed causes the UpdatePanel reload.
How can this be solved?
PS.: The UpdatePanel's UpdateMode property is set to Conditional.
