i got a strange problem. my project was ok before implimenting ajax. i have just implimented ajax in one page only with Tabcontainer and updatepanels only nothing else. almost all controls are devided into different Tabs with respective update panels.
mostly it is working ok. but the problem is :
1. in some controls i am not able to write anything even the control is "Enabled=True" and focus is on the same control after partial postback.
2. and as soon as i press Tab control goes to Address bar.
3. some time tab key is also not working.
here some code :
[Code]....
Here the Logic :
as soon as i type inception date; expirydate is automatically calculated and focus should come to sumassured. after this it should allowed to enter sumassured amount, which is not allowing to write.
As soon as i change tab and come back to original tab then i can write values normaly.
I've created a dynamic button from another control outside of the update Panel. The button is given an ID and such. When the button is click, a postback occurs and I've re-created this button during Page_Init, Page_PreLoad, and Page_Onload and NONE of them is preserving the value.
The only way for me to find the control was to look at the Page.request.form's allkeys and compare the string with a any text string that contains: Button. Because I ID'd teh button as: ButtonRow_0Col0. But the actual ID is null. However, when traversing through page.request.form, the allkeys shows that ID with no problem.
So how come the actual ID is lost after a partial postback yet, the page.request.form's allkeys can pull out its allkey's value??
I have a gridview that putted in ASP.NET Panel. both of panel and Gridview are in an UpdatePanel. there is a column in gridview that Causes Partial PostBacks. i want to Maintain Panel Scroll position on those postbacks.
I have a simple form (textbox, submit button) which is wrapped in an update panel.
[Code]....
I type some text in the textbox, click submit, then the server creates a database record and returns an object, which has properties like ID, Name, URL, Blah, etc. These are the values that the script requires.
So if i were to call a web service from the client-code, in order to get the values that were just created, i would need to do some hacks (get last record modified that has the value of the textbox). Not ideal, and neither is two AJAX calls for one form post. (update panel postback, then web service call).
I am having problems selecting the text within a TextBox in an UpdatePanel in IE 8. Consider a very simple page that contains a single UpdatePanel. Within that UpdatePanel there are two Web controls:
A DropDownList with three statically-defined list items, whose AutoPostBack property is set to True, and A TextBox Web control
The DropDownList has a server-side event handler for its SelectedIndexChanged event, and in that event handler there's two lines of code:
Now i am having two dropdown one is asp dropdownlist and 2ND is MultiSelect-DropDownList-with-CheckBoxes. 2nd dropdown is populating on selected value of first.On page load it works fine. Now, on change of value in dropdown, selected index change 2nd dropdown (MultiSelect-DropDownList-with-CheckBoxes) fills but i see a list box instead of dropdown.
I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.
How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?
I'm trying to place a user control inside an UpdatePanel.
When the control is displayed, typing inside the TextBoxes has a large delay while in IE (6 & 8). FireFow has an excellent performance. Not only typing, but also scrolling etc experience a large delay up to a few secons.
The usercontrol(s) contain quite a lot of javascript functions that are re-registered using the ScriptManager.RegisterScriptBlock or RegisterStartupScript functions.
why typing becomes so very slow? I believe it has to do something with memory leaking due to the re-registering of the jQuery functions. But I'm unable to find the source of it.
I am using a table and within the table i have gridview and textbox controls. On the rowcommand i am populating the data in text boxes. On top of the table i am using updatepanel for partial page rendering. When i select a row from gridview the text boxes are not populating, the table disappears.Below is the code
I want to make auto partial page refresh in asp.net. There is UpdatePanel but it sends too much data. So I've found that I can make a webservice and call it by the JavaScript code. But I don't know how to call webservice automatic. There are many examples showing how to call webservice by the button click event:

How to do this by the interval? Am I going in good direction?
I've implemented a Wizard in which most steps are UserControls. One of these steps contains a DropDownList and a RadioButtonList. Depending on the item selected in the DropDownList, some items in the adioButtonList are disabled or enabled via a callback. This works fine.
Then I added a ToolkitScriptManager to the page (EnablePartialRendering="true") and wrapped the controls in this particular step in an UpdatePanel's ContentTemplate. Running inside of VS2008, the appropriate radio buttons are disabled or enabled as expected in response to changes in the DropDownList without a full page refresh. It feels much more response and looks slick.
Then I deploy to the test server and suddenly the partial-page refresh is gone, the whole page is redrawing as though the script manager and UpdatePanel hadn't been added.
I've tried several variations on this, always with the same result. For instance - I moved the DropDownList outside of the updatePanel and added an AsyncPostbackTrigger for the DropDown's SelectedIndexChange event. No change - works in VS2008 but not on the server. - I added ChildrenAsTriggers="false" UpdateMode="Conditional" to the UpdatePanel, both with the DropDown inside the UpdatePanel and outside the UpdatePanel. No change - works in VS2008 but not on the server.
In ASP.NET, is there any way that on cue I can cause a partial postback with Javascript in an UpdatePanel?
I tried __doPostBack() but it does a full postback. I can trick it with a dummy button and fire click() then handle the partial postback that way, but I want a more graceful way than trickery.
Is there a difference, or are the terms synonymous? i could only find the difference between a full postback and a callback. I'm already aware of how a full postback is different.
I have this jquery functions below in external file. So after partial postback jquery is not working. I need to load jquery from server side on partial postback.
can someone show me what I need to call in this code and how to load jquery
I have a FileUpload control inside of an update panel that I would like to use to do async file uploads. The issue I am having is that during the partial post back, the FileUpload control is empty. I was under the impression that through an update panel doing the full page life cycle that it would pick up the use input.Am I incorrect here? Can this somehow be done or do I need to do the traditional full page post back to get this to work?
I have a page that uses AJAX updatepanels. On this page, we have some radio buttons with Autopostback set to true. The problem is that after the postback, the control was losing focus so that when the user would hit tab, control would be restored to the first control on the page and not the drop-down which fired the event. As a fix, I wrote some set focus code in the radio button's oncheckchanged event. This seems to have fixed the problem with the focus. The problem I have is that the browser loses its scroll position every time I click on one of these radiobuttons. Is there a way to maintain scroll position? Maybe there is another way to resolve my original problem of setting focus that will prevent this from happening.
i have one label out of update panel and one button inside update panel. in button click event i update the label text. when i run the code and click on button then partial postback occur and button click event fire but label value is not change. if i put the label too in the update panel then label value change at the time of button click. i do not understand why label value is not getting updated. suppose if i want that label should stay out of update panel and label value should change at the time of partial postback then how to write the code. i dont want put the label in any update panel.
i have some time consuming serverside function so i try to execute each function step by step and inform the user about the progress.
So my approach was:
create a visible button that performs an asynchronous postback and handle the click event on serverside execute the first function update a Label to inform the user if the function was executed successfully register a javascript that triggers the click-event of a second invisible(Style="display: none") button that is also registered as asynchronous trigger for the UpdatePanel send page back to client and execute script to click the invisible button handle the button-click, inform user, register js for third invisible button, execute button-click and so on...
But the problem is that the UpdateProgress-control will not be shown although i've set the AssociatedUpdatePanelID correctly. The functions are all triggered correctly and the labels are getting updated, only the UpdateProgress keeps invisible.
