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.

I'm using ASP.NET 4 to create a page with elements that are used in a jQuery UI Sortable plugin.
All of these elements contain a button (implemented as a submit button) with the name SubmitButton. All but one of these buttons are hidden in the page's Load event. But if I drag the element to another position, and then submit the page using that button, ASP.NET gets confused.
ASP.NET thinks I've clicked a different button, one that wasn't even visible on the page, but is associated with content at the position where the clicked button was before the move. (If I don't move the element, it works fine.)
I can't seem to determine how this is happening. As I understand it, ASP.NET knows which submit button caused a postback because the button's name and value is included in the postback data. (__EVENTTARGET plays no role here and is empty.) So how can it think a different button submitted the page?
How could ASP.NET get confused about which button submitted the page?
(Sorry, it's not possible to put this page on a public website.)
I worked through this issue and here's what I found.
First of all, buttons by default are rendered as <input> tags with type = submit. The postback mechanism in this case has nothing to do with ASP.NET. The postback data includes, among other things, the name of the submit button that caused the postback along with the button's text (in the form name=text).
But ASP.NET button names, by default, include the names of all parent controls. When those controls are unnamed, they are given an ID like ctl00, ctl01, ctl02, etc. The result is that all my buttons are guaranteed to have a unique name.
The problem is when these buttons and parent controls are all created dynamically. On the postback, these controls are reconstructed in the load event but in the new order. Because the order affects the name (ctl01 vs ctl02), this means my submit button has a different name than it did when the page was originally rendered.
The result is that ASP.NET sees the wrong name associated with the submit button used to trigger the postback.
Hii.
In my project, in the main page, I've a ASPxPageControl and ASPxPopupControl. In the ASPxPopUpControl, I've a form consits of two radio buttons and so many text fields and combo boxes etc. In the ASPxPageControl, there are two tabs.
The PopUpElement of ASPxPopupControl is in the second tab. And on the PageLoad(), I've configured to display the first tab.
I want to enable/disable texbox in the form according to the user selection of the radio button. But, when AutoPostBack is enabled, the entire page is refreshed, and the default tab will be the first one. And to resume the form, i've to manually click the second tab and the ASPxPopupControl will open automatically.
Is there anyway to resolve this?? Is there any other control other than radio button to do this?(Which accepts client side scripting)
Firstly, Do you need to postback to enable/disable textboxes? you have rich ClientSide Events for Textboxes to enable/disable/hide them (SetVisible, SetEnabled).
Secondly, you can have your second Tab Content in an AspxCallbackPanel, and when Radio Button changes, you Can do a CallbackPanel Refresh (PerformCallback). Thus, only the Tab Content will update.
I have on server control(dropdown) and One button.user can select some values in dropdown and click button.I have to show a pop-up.In this pop-up I have show data based upon value selected in dropdown.How to access a dropdown in codebehind of pop-up screen.I am loading a .aspx in pop-up using javascript.
Why not just pass the selected value of the dropdownlist as a querystring parameter to the popup page?
That's the way i'd do it.
If you dont want to do it that way, you can access the parent window by using window.opener.document.
So something like:
window.opener.document.getElementById('yourDDLId').value;
Still i'd recommend passing through as querystring param. Simple and easy.
I have a ASP.net page with couple of tabpanels. When a user hits submit button when he is on the First tab I am showing the user the second tab control. Ontabindexchanged I am dynamically creating a usercontrol and passing some values to the control.
Now when the user is in the 2nd tab and if he navigates to the first tab, I need to pass some values to the first tab.
At the tabcontainer level how do I pass values between tabs?
I think what your problem is, you need to maintain viewstate of your dynamically created controls, otherwise there is no problem to pass values between tabs. like..
tab1TextBox1.text=tab2Textbox2.text (Since your controls are in AJAX tab panel, no need to find control from tab panel)
For Maintaining viewstate of your dynamically created user control, you need to create your control in page_init() event.
Here's the situation.
When a user is editing a given piece of data, they're allowed to add messages/comments. These are stored as child records in a SQL database. Clicking on the Add Message button brings up a panel (pnlMessage) courtesy of the AJAX ModalPopup Extender. This takes some input and, when the "Send Message" button in the panel is clicked (I learned the hard way to NOT make that the 'OkButton' property), the message is stored in the database and an email is sent to the intended recipients. No problem there.
However, I need to be able to allow the user to add new email addresses (so long as they are registered in our database). I have another ModalPopup / panel combo (pnlSearch) that's tied to a button on the previous panel (pnlMessage).
The user is supposed to be able to add an email or click on a search button to populate a list to choose from.
The pop-up panel (pnlSearch) comes up just fine, but clicking the "Lookup" button (which instigates the search and returns a collection of records that the user is supposed to pick from) closes the panel.
Previously, I ran into the problem of having the Button.Click event never firing when I put the Button into the "OkControlID" property (the CancelControlID works fine since I don't want to do anything). Removing the "OkControlID=Button" line allowed it to work perfectly with the Button.Click event firing as expected.
So now I have the Search panel with a button for "OK" and a button for "Search" - but the panel should stay up and visible after the Search.Click does it's thing. Am I missing some property that basically says "don't close the panel when this button is clicked"? Of course, if I bring up the panel again in the same session, the results from the previous effort are there (the search results).
I'm trying to avoid having to go to javascript as there isn't much, if any, of that experience available to support this.
Help!
Thanks in advance.
You can put the Search panel and the Search button inside of an UpdatePanel. Anything inside of the UpdatePanel will be able to post back without closing the popup. Be sure not to put the buttton that is supposed to close the popup inside of the UpdatePanel.
