AJAX :: Validation Summary In JQuery Dialog Modal Popup Box Not Working With Update Panel
Dec 23, 2015
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:
The WebForm_OnSubmit() function is being rendered by the BaseValidator control and in the form tag te following attribute is being added: 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.
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 button Import on my page. Upon pressing this button, a modal popup dialog appears where the user can enter path of the import file. I have a required field validator to make sure the user entered the path. And I have there a Submit button. My problem is that validation happens not only when I press the Submit button on the modal popup, but also when I press any button on the page itself, which is wrong.
I have a textbox txtPctDown inside an update panel. On textchanged, a sub is called that does a calculation and puts the result in to a label in a modal dialog. When the text changes, the sub is reached but the modal dialog doesn't appear. if I eliminate the UpdatePanel then everything works fine. I tried with an without using the textchanged as a trigger.
How do I get the modal dialog to appear when the text changes?

The validation summary is inside a div which I'd like to show as a modal message using the jQuery UI. The problem is that I can't figure out how to execute the javascript when the ValidationSummary is shown.

Modal popup not working, I need to open modal pop up inside a panel, below is my html, senerio goes as :
On page load on only panel with id="pnlgrid" is visible and button with id btnaddnew is visible on clicking addnewbutton panel grid is visible false and panel with id=pnlFormEdit is visible true.

I 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.
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 details
On particular client selcted above.
I have given the delete station command on deleting the station that particular entry doesnot goes away.
It Should not be visible after it get deleted
Now when i click on imagebutton a modalpopup will open.
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 am using two update panels in a page. Both of them are conditional mode and display when a checkbox is selected. So far it is good. I have few textboxes in the the second panel and I want validations to be set on those text boxes on a condtion, ie if textbox 1 is not empty then textbox 2 's required field validatior should trigger and viceversa. I have written the following logic in the pageload method,
At first I had implemented the following Code for Jquery Validation. URL....It is working fine without UpdatePanel. But with UpdatePanel the Error messages are showing then also Page PostBack occured.

I'm using modal popup extender and panel with calendar in it. Click the "Next / Previous Month" closes the modal popup. How do I tell the modal popup to ignore click events in a calendar control inside the panel targeted for popup? I'm confused because when using extender before, you had to click OkButton or Cancel to close popup. I have update panel for reason. I just minimized the code for easy review.
I am exporting a datatable to an excel sheet. When the ExportToExcel event is fire it pops up a "file download dialog" asking if I want to open or save. What I want to do is right after user clicks on open, or save I would like to show a modal popup saying "Do you want to finalize this download?".
Here is some code, it all works except it won't show modal popup after exporting to excel. Why won't mpeFinalizeDownload.Show() run unless I comment out the line above it?
I have a test page with links that open a panel modally (using AJAXControlToolkit: ModalPopupExtender). I am using an update panel. After clicking any of the links about 10 times, the popup is shown buried under the links (and is not accessible). When I limit the content on the page, the number of times is extended. My thought is that this may be a "data limit" in relation to the update panel, as this works fine when the update panel is removed. I would love to post the code, but this form won't let me. I can certainly send the webform if anyone is interested.
here when I click on button it will show popup but I want if users don't type any text in textbox if they click on button it doesn't show popup and show error that I define in RequiredFieldValidator...here when I don't type text in textbox when I click on button it show both(popup and Required FieldValidator) but I want it doesn't show popup untill I type text in textbox...
