Postback issue - ASP.NET - .NET Framework

6 New Member

Hi there. I'm having an issue with autopostback, in that it doesn't seem to be working!
The webform I am using pulls the data from an AccessDataSourc e to populate the gridview, which has Edit and Delete functions. I have also configured it so that I can insert into the gridview using the footer row.
What I am now trying to do is create two searchable dropdowns in the header of the first two columns (company and reference) that would just return the chosen results, but when the options are clicked, the page just refreshes. Have trawled the internet and various books, but seem unable to find any answer; I think it's the way I am creating the dropdown? Since I've never been able to get a dropdown to filter the gridview.
I am using VB/.NET 2.0 and Visual Studio 2005. Any help as to why my postback isn't working would be fabulous!

Hi,

Declare all the dropdown lists as Static(Shared) and try.

Eg:

Shared column1 As DropDownList

PostBack IFrame src issue

by: Rhys | last post by:

I have a page which has an IFrame on it. The src of the IFrame is a page with a datagrid on it. The Datagrid has bound template columns. The columns of the datagrid pass the bound data value of each cell within it to my code behind file which generates the HTML to display the data in a formatted text box, some of which is editable, some of which is not.

Postback won't trigger

by: Anand | last post by:

Hi All, The postback on my desktop stopped working. I am trying to run the webapplication locally on my desktop and the Postback on my home page won't trigger on any of my dropdown selections. The error on the displayed HTML points to the line in the PostBack event which is not my code but the auto generated code for the postback event. Have anybody else faced this issue. Any help appreciated. Thanks Anand

Atlas Postback Problems

by: Jason | last post by:

I have a webpage that I've wrapped in an Atlas UpdatePanel. This page contains four textboxes, each with AutoPostBack set to true. The problem comes when someone edits the first box and tabs to the second box. They have enough time to make a quick edit to the second box before the postback completes and then the value in the second textbox is reset to the original value. Is there anything I can do about this? It's really causing...

What is Postback?

by: antonyliu2002 | last post by:

I know that this has been asked and answered thousands of times. As a matter of fact, I know that I need to say If Not Page.IsPostBack Then 'Do something End If for things that needs to be processed by the web server. I am still struggling to understand this postback logic, and hope that some kind gurus out there could help me clarify the confusion I have.

by: =?Utf-8?B?SlA=?= | last post by:

Hi all. I'm having a problem with a postback issue and I think it's cache related. Here's my setup: I have a web site that has a signup section. This has simple things like name, age, birth date, etc. When the user visits this page for the first time, a person's data object that is used to store the user's name, age, birth date, etc. is created and stored in session. On the first visit to this page, the object is empty. Whenever the...

Postback nightmares

by: Doogie | last post by:

Basically, I have two custom dates the user can enter via a popup calendar. These dates are stored into text boxes. Then the user can click a button (Run Report) and those values (as well as others) are used to build an SRS url string. This used to work before I modified the page to make the calendar a popup. Now, the text boxes lose their value when the user clicks the run report button. I have verified this is happening because...

The easy way to turn off automatic updates for Windows 10/11

by: Hystou | last post by:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
