AJAX :: Tab Container ActiveTabIndexchanged Event Not Working On Serverside

Apr 4, 2010

I'm having asp.net ajax tab container in a datalist control with 4 tab panels. I set ActiveTabIndex to 0 on .aspx page, and using OnActiveTabChanged event in code behind, when the tab container tab index is changed, server side event is not working, when i debug the code, i can see the event is getting fired, even though i click the third tab, i'm getting Active TabIndex "0" only.

<cc1:tabcontainer
id="TabContainer1"
runat="server"
AutoPostBack="true"
Font-Names="Calibri"
ActiveTabIndex="0"
Width="710px"
CssClass="yui"
align="left"
OnActiveTabChanged="TabContainer1_ActiveTabChanged">
Server Side Code:

[Code]....

I need to load data only when tab index changes, this way i can reduce burden on whole page.

I'm trying to get a page working using a tab container and multiple tabs. So, I created a new blank page and pointed it to my master page. The master page has two content panels within it.

C# - How To Call Silverlight Handler Event And Then Serverside Event On Page Submit

Mar 19, 2010

I have a Silverlight control on page which has a upload control. the silverlight exposes some events such as

StartUpload() => To start the file upload,

StopUpload() => To stop the file upload if running,

CheckFileStatus() => to check the status of the file upload.

The page has aspx Submit button with onclientclick event and ocClick event.

<asp:Button ID="btn_upload" Text="External Upload" runat="server" OnClientClick="Javascript:StartUpload();"
OnClick="btn_upload_Click" />

When I click on the aspx Submit Button, the file selected in Silverlight control should be uploaded and after the completion of upload, the Server side event should get called.

Web Forms :: Bypass The Textbox Textchanged Event On The Serverside?

Jan 20, 2010

i have a gridview with commandbutton column and a textbox template column. My requirement is changing the text and hitting the enter key should also perform the same function as the command button. So i enabled the autopostback of the textbox.But if i click the command button after changing the text in the text box fires both the TextChanged event as well as the item command event. Is there anyway to bypass the Textbox text change event if i postback using the grid command button?

Web Forms :: The Serverside Event For The Button Is Not Triggered And PostBack Is False

Nov 18, 2010

I have a problem with the ASP FileUpload control. It occurs in Safari and on websites where anonymous authentication is disabled and windows authentication is enabled.

When I select a file in the upload-control and then press an ASP-button the serverside event for the button is not triggered and PostBack is false.

Steps to reproduce the error:

1. Create a page with a file upload and a button. Print a message in the page's load event so you can see that if postback is true or false

2. Open IIS-manager and Add a new application that points to the folder where the page is

3. Disable Anonymous Authentication, ASP.NET Impersonation and Forms Authentication for the application

7. Enable Windows Authentication for the application

8. Browse to the page with Safari

9. Select a file with the upload control

10. Press Ok. Postback is false

If you then enable anonymous authentication on the web application and restart the browser postback works as expected.
