Use Update Panel To Run Some Server Sided Code
May 19, 2012
I am trying to use an update panel to run some server sided code. everything works fine with this:
asp Code:
<script runat="server">
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Label1.Text = "Refreshed at " & _
DateTime.Now.ToString()
[Code] ....
The problem is this: when the page first loads, i have a text box that i add a string to. if its a normal string, its fine. but, if its an XML string, the update panel will stop working (no errors, it just wont refresh the panel when the button is pushed). i'v tried narrowing the cause down and found it does not like "<" character.
I tried using this: Server.HtmlEncode to encode the xml but there must be other characters in the string it does not like (the XML is a response from the Linkedin API) .
how i can remedie this? even if the Server.HtmlEncode worked, its not the ideal solution, as i want to display the XML not the decoded string.

We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.
Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
How do we achieve this ?

I am doing a countdown with a timer that runs every second. I have a scriptmanager, but how do I make it update behind the scenes so the user does not see it? I thought I could use an update panel, but I can't get it to work right.

I've the Javascript code to do a confirmation before deletion of some records
function confirmDelete()
{
if(confirm('Delete all?'))
{
return true;
}
else
{
return false;
}
}
I've the button code here
<asp:Button ID="btnDelete" runat="server" onClientClick="return confirmDelete();" onClick="btnDelete_click" />
If i've the button outside an update panel (basically i'm using RadAjaxPanel by Telerik) it is working fine. But when the button is inside an ajax panel, even if i click OK for deleting the records the server side code is not called.

I am passing the PageNumber and PageSize to a stored procedure, which returns only that page of data. It also returns a record count what the total number of records would be if I returned all of them at once.Generally, how do i hook this up to the DataGridView to enable paging?It seems like the expectation is for the resultset to contain the complete dataset. Many of the properties that I expect to be able to set, like RecordCount, appear to be read only.

I have a panel withitn an updatepanel with some buttons.
When one of the buttons is pressed, I'm updating a different update panel.
The problem is that when I click the button, nothing seems to happen.
If I click the button again , then I see the first update. If I click it again, I see the second update and so on..

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):

I have created a custom required textbox control. In this control's preinit event i load a css file. Alle css and images are inside the assambly. When i use my custom control on a page the control loads fine and also the css and images are loaded. Validation of the control occures when i click the validate button. So this works perfect. But now i want to use my control in the following senario: I have a grid in an update panel. When i select a record in the datagrid i show a panel in a second updatepanel. Inside this panel i have my custom required textbox control.
The following is happening: I select a record and the panel will be made visible. The custom required textbox control is visible, but the build-in css is not loaded. As a test i have created a new testpage. On this testpage i have put my custom required textboxes in an updatepanel the css is loaded fine. So when my controls are in a panel inside a updatepanel and i set the panel to visible, the css is not loaded.

i have my master page with one update panel working like a banner, so when the timer do tick every 5 sec
the image change. That works fine, but i have an update panel in my index page, this update panel works with some buttons that change the text inside the panel when click.
Now, the problem.
When i click one button to change the text and the banner change, the text returns to his default text. The update in master page is affecting the update on index page.

the site normally works fine in all popular browsers including firefox, chrome, safari and ie.
but doesn't work in ie 8 when it's redirected via a proxy server and it gives an error saying
"Message: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

I'm creating an ASP.NET Control which has a property collection for Columns which the user can edit in the Property Collection Editor..
In most circumstances this works fine, the collection can be edited in the designer and the appropriate tags are added inside the control in the ASPX file.
It works fine when
My control is added to the form
[Code]....
My control is added inside an Update Panel
[Code]....
[Code]....
However, if My control is inside a Content Placeholder which is inside an Update Panel, it fails to work as it should. In this scenario, when the Columns collection is edited in the designer, if you then switch back to Source view, the Columns collection is emptied. I have to save the aspx page before switching back to Source view for the changes to be kept.
[Code]....
how to get around this problem? Is there something I may have missed?
Here's the code for the Control
[Code]....

I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.

I am using asp.net 3.5 c#. I am trying to do this:
In one page, a user can insert some stuff (name, phone .. etc) to the database. And then the user should be able to see the rows he added as a list automatically in a datalist (or other control). As he inserts rows, it appears in the datalist.
I tried to use update panel and inside it datalist, with a button as a trigger but it did n't work with me!
