I am using AjaxToolJit Tab Container and the problem is when i refreshes the page the default tab is set to 0 but i was in 4th tab when i refreshed the page.
AutoPostBack=true
help me for a while but when i used UpdatePanel in the same page causes the same problem again.
If you need to keep selected tab index across full post back or page refreshing with F5 button then you must save selected tab index in session on SelectedIndexChanged event and then use this saved index value in Page_Load event handler

I have a project with a drop down and a button to refresh page.
I want to refresh page by selecting item from drop down list without using button to reload query.
You can use the drop down list's OnSelectedIndexChanged event to check the selected value and call the buttonclick event of the refresh button
You can use AutoPostback = true in the details of the dropdown. When the OnSelectedIndexChanged gets fired the page automatically reloads.
I have an updatepanel with multiple Dropdown. When user select value from the dropdown and hits save button (which is outside updatepanel) immediately, the dropdown previous selected value data is getting displayed instead of loading new value data.
So how to stop postback (save button) until updatepanel data gets loaded.
Thanks in advance.
UseSubmitBehavior="false" on the button will stop postback from happening.
I have a page (page1) with a LinkButton that, when clicked, will take the browser to a new page (page2).
When I click the LinkButton page1 posts back and hits the Init and Load event handlers for page1, and then moves on to page2.
How can I tell in the page1 postback that I am about to be taken to a new page, as opposed to clicking a Button that causes the page posts back but does not navigate away?
You can also add OnClick events to your code behind for each button, and in the case of the one that is to postback to another page, do a Response.Redirect. The limitation of that however is that if you need form data on "page2", you will lose posted form data on a Response.Redirect.
It appears that you're not using the OnCLick event of the LinkButton, If you use the event, perform the action of the click there, not on the Page Load event?
There is a tab menu which was created by asp.net control. Now I'm changing this with a new tab menu I made with javascript. There is an event on third tab and when i click the tab it's posting back with asp.net ajax as asyn. but it takes me to the first tab after postingback every time but I don't want to change the tab after this. it must be stay on the third tab just must be changed content that's all. How do I solve it?
thank you
If your home-made tabset is in the update panel, then it will be part of the partial update. Your tab control needs to remember it's viewstate so that when it is rendered after a postback (or partial update) it will render with the right selected tab. I suggest using a hidden field on the page that holds the value or index of the selected tab. Then, when you go to render the tabset from a postback, you read from that hidden field and know what tab is selected and render as such.
How do I force a CascadingDropDown to refresh it's data without a page refresh? I have a button on the page which adds a variable to the Session which is then used to set the selected value of all the drop downs. However I can't seem to force the refresh of a DropDownList without a full refresh of the page.
Let's see - the button on your page probably has an event associated with it to respond to it being clicked, right?
Can't you just reload and re-assign the data to the dropdown in the button OnClick event?
public void OnButtonClick(.....)
{
.....
CascadingDropDown.DataSource = .......;
CascadingDropDown.DataBind();
}
Or am I missing something?
