I have a gridView and on the DataBound event I am assigning a Session variable from one of the gridview results. This session is then used to determine if certain nodes in a menu are visible. One problem is that when the session variable is assigned, the menu is not updating, until either I refresh the page manully in the browser or move to another page.
View 3 RepliesI have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.
Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)

I have a control on a page. In the control's pre-render event I'm executing some code that's taking about a minute to execute. This means the whole page is unresponsive until the control's pre-render event is finished executing.I tried putting the control inside an update panel, but it doesn't matter the rest of the page still won't render until the pre-render event of the control is finished executing. I've attached a very simple example of my code (The event that's slowing up the control's pre-render event is not Thread.Sleep(1000):

But i got same error. how I can add to my Update Panel that Button from Content Page can refresh it?
I am dynamically ading the following to an UpdatePanel
Tab control which has X# of Tabs, each Tab has a various labels and a Rating Control.
When the user hits the Rating contro, the RATING_Changed fires and runs a stored Proc to update the DB. I want the Panel to then display the newest information back from the DB. I can't seem to get the last part to work. I'm still learning .NET so i may have missed somethign easy, but i've tried setting AutoPopstback, using Triggers, etc.
The DB Update does take place but the NEW contents are not displayed

How to refresh the update panel on timer_tick event???whats the code for that..?
View 3 RepliesI am developing an application using Visual Studio 2010 and SQLServer 2008. My application has two pages and the first page contains a GridView with all the records "User Administration" and when user click on any Username (template field ->linkbutton) I read the USERID like this.
Session["UserID"] = e.commandArgument;
Response.Redirect("UserOperations.aspx");
which takes it to the Data Entry page where user updates the information and save the data.
The problem i am facing is that when I hit the browser REFRESH button couple of times the session variables looses the value which is trouble for me as I am using Session Variables for different purposes.
on page refresh it redirects to login page. why?
View 1 RepliesI have a number of cascading dropdownlist controls on a page. The results in dropdownlist2 are dependent on the results in dropdownlist1, pretty basic stuff.
I now would like to eliminate the terrible postback or refresh of the page that occurs after the SelectedIndexChanged event fires on dropdownlist1, is it possible to do that in Ajax?
What I want the results in dropdownlist2 to populate without the obvious refresh of the page.

View 1 RepliesI was working on this last week and took a break from it to 'regroup' and start over. Here is what I'm trying to accomplish.
1. have a web form with dropdowns to allow the user to select font sizes, colors, background image, etc.
2. I want to the form to be updated with the new styles in an update panel.
3. Once the user clicks the apply button, I want the updatepanel to refresh with the new styles.
I tried this by creating an css on the fly, but the updatepanel wasn't picking up the new css without doing a full page refresh, (which we don't want to do). I only want the updatepanel refresh and either use inline styles, a <style> on the web form etc,
if i use a combo box inside an update panel, the updatepanel's partial postback will not work. instead in a postback the page refreshes whole.

View 7 RepliesI am trying to refresh updatepanel using dropdownlist but facing problems.

<asp:AsyncPostBackTrigger ControlID="ddlClass" />

<ContentTemplate>
<asp:Repeater ID="rep1" runat="server">
[Code] ....
This is updatepanel code. as shown in the code, i am referring to ddlClass in triggers which already calls a javascript function loadAllDefaults();
The problem is, since ddlClass is calling javascript function 'onchange' property, i cannot call any other function of backend code and I want to refresh the updatepanel on the basis of selected value of dropdownlist.
How can i do this? I have created a function in c# code in backend but I am not able to call both functions together!

View 3 RepliesI have found an odd bug in my application. I have a dropdown status which is bound to my gridview. On selecting a status from the dropdown the selectedindex then fires and binds the results to the gridview.Now the strange behaviour in firefox and not IE:If I have a dropdown open and an ajax update fires on my gridview the option is selected from the dropdown (just by hovering my mouse over it rather than selecting it) and the results bound to the gridview. This does not happen in ie as you should have to physically select an item from the dropdown rather than firefox selecting it for you because you happened to hover over an option when the update event fires.
