But user enters the wrong detail, it should shows in a lablel in a popup panel. It shows; but the problem is it close the popup . But I want to keep the popup if the user enters the wrong details. How can I do this?
View 5 Repliesi am confused about the fact that if partial update of dropdowns is possible through Update Panel ,then why we should use asp.net ajax Cascading drop down extender ,that has made same task bit complex by making callback to web services ? what is difference between using update panel and cascading drop down extender ?

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.
I have 4 modal popups on a form and one of them have update panel, inside that update panel i have some form elements such as label and text boxes and one reset button.
Reset button will clear the data of form elements and i kept that button as AsyncPostBackTrigger for that update panel.
But when i click on that reset button it opens all other modal popups also
I'm doing a website with Ajax and Framework3.5.
I have a update panel inside a modalpoupextendar which is in another update panel.
When user need to click the button in the parent update panel the modal popup will appear,
then in the popup if user click a button there I Need to show some text in a user control which placed in the panel.
See the html tag and tel me any solution. Its not working for the first click its working in the second click only.

The subject is explanatory, but here are some details:
I want to update a repeater when SelectedIndex value changes for a dropdown list. The problem is Nothing happens.
My aspx page is present in a nested master page. and neither autopostback works nor update panel. i have set the AsyncPostBack trigger on SelectedIndexChange event.
Please let me know what am i doing wrong or what am i missing.
PS: I have never worked on ajax before so I might have overlooked something.
I am using cascading dropdown list where the no of dropdowns is created dynamically on the page. The cascading drop downs are contained in a User Control. I need to call a method from the Parent page which will be executed when the values in one of the dropdowns change. The server side event is not firing as I have set AutoPostback property for the dropdownlists to be false. How can i make the Page event fired from the Selected index changed of the dropdowns keeping the autopostback property to be set as false.
View 5 RepliesI have an ajax modal popup extender in update panel. The modal popup extender has a label, checkbox and a dropdown list. When i open the popup first time (i.e Page_load) and select something and click on ok the data is populated correctly in another grid. If i open the popup second time and select some data and click on ok it is populating the grid with the current selected data as well as previously selected data.
View 3 RepliesI have found an odd bug in my application. I have a dropdown status which is bound to my gridview. On selecting a status from the dropdown the selectedindex then fires and binds the results to the gridview.Now the strange behaviour in firefox and not IE:If I have a dropdown open and an ajax update fires on my gridview the option is selected from the dropdown (just by hovering my mouse over it rather than selecting it) and the results bound to the gridview. This does not happen in ie as you should have to physically select an item from the dropdown rather than firefox selecting it for you because you happened to hover over an option when the update event fires.
View 4 Replies I am sending you the code. It Has two PArts First is CLIENT SECTION and Anpother is STATION Section
1) CLIENT SECTION : It has a dropdownlist binded to SQLDataSource and with this it has an imagebutton bAddClient
bAddClient will open the ModalPopup which will ask user to Add new client. And After Adding the New client when User
will close the ModalPopup MY DropDownList is not getting Populated with the New Client. I have Used UpdatePanels Also
2) STATION SECTION : It has a DropDownList, an Image BUtton , And Grid View. In Grid View it shows station detailsÂ
On particular client selcted above.
I have given the delete station command on deleting the station that particular entry doesnot goes away.Â
It Should not be visible after it get deleted
Now when i click on imagebutton a modalpopup will open.Â
Now In modalpopup i have given dropdownlist , image button(to add new station), Some station Info and save button
Now when i click on dropdownlist it used to close the modalpopup then i seet the autopostback = false. Then it works fine. Is it correct way?
Now when i click on imagebutton it asks user to add new station with a textbox , save station button. When users click on savestation button then it adds station to the DB and it should update the dropDownList of ModalPoup without closing it.
But when I am clicking on imagebutton it is closing the modalpoup.
And When user clicks on ModalPoup SSave Button in end it should update GridView of STATAION SECTION too.

I'm using the ASP.Net Validation controls and I want to display the Validation Summary in a JQuery Dialog instead of the native javascript alert messagebox. I've found this solution (aspsnippets) by overriding the clientside WebForm_OnSubmit() function:
<script type="text/javascript">
function WebForm_OnSubmit() {
if (typeof (ValidatorOnSubmit) == "function" && ValidatorOnSubmit() == false) {
$("#validation_dialog").dialog({
title: "Validation Error!",
modal: true,
resizable: false,
[Code] ....
The WebForm_OnSubmit() function is being rendered by the BaseValidator control and in the form tag te following attribute is being added:Â onsubmit="javascript:return WebForm_OnSubmit();
I am running into a problem on a page which has an UpdatePanel. The input field with the validator (1 to make it simple) is in a Panel within an UpdatePanel. The Panel is set to Visible=False at the first Page Load. There's a button inside the UpdatePanel which makes the Panel with the Validator Visible.
When this happens, the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag are not being rendered because it's an AJAX callback and the form tag is outside the updatepanel (in a master page), so the validation summary will not be shown in the jquery dialog.
Validation is being performed, so the validation summary wil be shown in a div on a page, but the validation is not being called by the WebForm_OnSubmit() function in this case, because it's not being rendered.
Here's the markup of the page:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="btnNew" runat="server" Text="New" />
<asp:Panel ID="pnlEdit" runat="server">
<table>
[Code] ....
So, when the validators are not visible at the first load and they will be made visible by an AJAX callback, the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag are not being rendered on the pag. Because of that, the WebForm_OnSubmit() function will not be called and the validation summary will not be shown in the JQuery dialog (although it is being shown in a div on the page). How can I get the Validation Summary to be shown in de JQuery dialog in this case?
Is there another function that has to be overriden for this case? I know I can use a Full Postback for the New button and then all the stuff needed is being rendered on the page, or I can make the panel not visible by using a style, but I don't prefer that because there are a lot of pages with this situation.
One solution is to use a dummy textbox with a dummy validator (with a dummy validationgroup) of which I set the display to none. Then this dummy validator will cause the the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag to be rendered.
I have a user control, that has an update panel and update progress control in it.
I use this user control in more than 1 location on the same page.... problem is, when ucA posts back, I see the update progress control for both ucA and ucB. I assume this is because it is a user control and the update panel and progress are named the same?
Either way - how do I make it so that the update progress only displays for the proper user control?
I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.

Now i was trying to use an UPDATE PANEL, in order to when i click button Save, only the DIV updates. Because the whole DIV is closing when i click on SAVE, even if i put a div in an update panel.
is there any other way by which we can update a section in page except Update Panel?

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 trying to display an model popup to update records. data is stored in msaccess database.
Here i need to show popup filled with exixting data when i click on edit button inside edit column of grid.
once user modifies data and clicks on save button within popup data should be stored.
I have masterpage which includes dropdown list for choosing skins for page.
Also I have Home.aspx include above master page. This Home.aspx contains update panel[up1] which further comprises of gridview, link button, image button[IB] and dropdown list. Also there is one modal popup that has a panel which includes dropdown and text box.
Requirement: when i click image button[IB], modal popup opens up and home.aspx gets grayed up.
Issue: when i click image button[IB], modal popup opens up, but all dropdowns placed in[Home.aspx and Master page] get disappeared[invisible]. Once i close modal popup , they are visible.
I have three drop downs in One update panel based on which Text box(in second update panel) value will get updated which is date basically. now when i change the value of text box the values in the drop down should get populated as well. While Selecting the values in drop down and textboxes the dropdowns keep on flickering. Do I need something extra so that Dropdowns wont flicker...
