AJAX :: Hidden Fields In Gridview Inside An Update Panel Not Refreshed?
Jun 22, 2010
I have a user control which has a gridview with hidden fields in some of the template columns. The grid columns are created and bound by code dynamically in each postback and not in design mode. The gridview is placed in an update panel. In my aspx page where i use the user control , there is a dropdown which fires postback and based on the selected value of the dropdown the grid data gets filtered. The dropdown in aspx is not part of any update panel.
After the postback of dropdown, the grid data gets filtered and the grid is rebound with fresh values. The values in the controls like label, button or link button are bound correctly. But the values in the hidden fields are not refreshed and always points to the values of the rows that was generated before the postback of the page (initial page load).
I have a web application project, in which i have 2 projects one is for my UI and other for dealing with database. In UI i have a page on which i have used update panel and script manager, the usual procedure, but surprisingly update panel is not working my page is getting refreshed.
i hv a gridview in modal popup,I hv taken checkboxes in itemtemplate and written code in javascript function to checked or uncheck the checkboxes.and in pageindexchanged event calling that javascript function to maintain the state of checkboxes.it is working fine.but when i put it inside update panel nothing is happening.
Looking for the best technique on handling or at least some documentation showing an example.
Starting Page
Gridview control withing an update panel (also various controls used for filtering NOT IN UPDATE PANEL)
Databinding does not happen during page load.
Databinding is initiated when update panel trigger (asp:Button object) is clicked
Hyperlink column is added to returned records
Hyperlink posts to a separate page for detail for record which the hyperlink was clicked.
Second Page
While navigating via the browser back button to previous page (which contained the update panel and gridview) only the (various controls used for filtering) have retained state. The gridview is not shown (which is how the page loads initially when starting) How can I retain the state of the Gridview and add a step in the browser history all together?

I am trying to implement validations for a jQuery pop-up which is placed inside an update panel. I am facing problems using validation controls and I presume its because oft he ClientScriptManager it uses. I read in the FAQ section [URL] that we need to download and apply a hotfix to solve this.
Having a bit of trouble here. I know that if you want to use a fileupload control inside an AJAX update panel then you need to create a trigger for the control that performs the uploading postback to the updatepanel, but the problem is, I have an update panel that contains web usercontrols. I therefore can't add a trigger to the control(FileUpload) directly because it exists in the web control.
I have a check box, RequiredFieldValidator and textbox that have editmask extender I want to change the control properties programmatically when I check the check box but the problem that nothing happened when I check it.
I made the control post back and I added triggers.
when put break point and go with code step by step will go through the code but nothing change.
i have an issue running JavaScript inside an updatepanel,
i'm using a script as follows:
[Code]....
and each time the update panel updates i load a new variables for the FlashFileName to display a different movie.
outside an update panel this works, but inside the script doesn't run, i have read on other posts that there is an issue with running javascript inside an updatepanel.
I have an application that allows users to insert data into a log. The forms are displayed inside update panels and display via modalPopUpExtenders. I am running into a problem where users are able to click the Insert button multiple times before the panel can update that a click was registered.
How can I disable the Insert button once the user clicked on it and had time to communicate with the server? The system is allowing duplicate and triplicates to be inserted into the system.
2- i have Ajax Control ToolKit HTML Editor OutSide My UpdatePanel and its not inside any control.

I have a page with three update areas, Create, Edit, and Delete. The controls that do these three functions are inside separate update panels so when I'm doing Create, I only fill controls inside that updatepanel. Problem is I'm using asp validation controls on all the controls in the three areas. Therefore, when I press the "Go" button in the Create UpdatePanel, the validation fails on the empty controls in the other two area. I hope I'm explaining this well. The behavior I would like to see is that only the controls contained in the updating panel would be validate.
have a wizard control inside an update panel. have a radiobuttonlist that autopostback's when i click a radio button, page posts back & the page hops back up to the top. i want a user to be able to click radio controls & checkboxes with the form to be fluent; the hop back up to the top is rather annoying & may confuse the user.
have update panel that content check box, textbox, 3 DropDownList with CascadingDropDown extender. When I checked the checked box it should do a AsyncPostBackTrigger and it is working ok but the problem that if I select any thing from DropDownLists then check the box it would clear the DropDownLists after doing AsyncPostBackTrigger for the the check box.
any advice how to separate these controls inside update panel for doing AsyncPostBackTrigger??
