AJAX :: Edit ModalPopupExtender In Gridview Control?

Feb 24, 2011

I have created ObjectDataSource control which is bind with the GridView control (In few cases with DetailsView control) as well as I have created new column "Edit" in gridviw with Linkbutton.

Now whenever user clicks on linkbutton it shows ModalPopupExtender with edit fields for that particular selected gridview row.

My problem is that I want to show only few columns in gridview (eg- EmpID, EmpName) and want to edit all columns in modalpopupextender (eg- EmpName, City, State, Pincode etc).

So how can I show all the fields in modalpopupextender to edit becouse when I am reading fields from GridViewRow not able to get the hidden fields which is not included as columns in gridview?

Somehow can I read fields values from ObjectDataSource?

AJAX :: ListBox ListItem Edit Via ModalPopupExtender

Mar 17, 2010

I have a listbox. There is an edit button beside it. When users select an item from the listbox and click the edit button, a modal popup extender pops up. The modal popup extender contains a textbox and a button (edit). When they edit the content, they canclick the button again, which will close the modal popup extender and update the text of the selected item.Users want an option to add '<br />' to the item in the listbox, so when the text from the listbox item is displayed in some other page, it shows up in multi-line format. However, when I add '<br />' to the edit text and hit the edit button, I get ajax error that does not close the modal update or edit the text in the listbox. However, if I type in '<>' or just 'br /' in the textbox and click th edit button, it works. In fact any text inside the < and > triggers the error. Here's the error I get.

AjaxToolkit ModalPopupExtender - How To Set Focus To A Control In The Popup Panel

Jan 7, 2010

When the user pushes the Button, I'd like to display a modal dialog box to capture a couple of values from text boxes and submit these values to the server. When the modal box is shown, I'd like the cursor to be placed in the txtFirst textbox. How do I do this? I've had trouble with registerscript commands before, so if one is needed, I hope the syntax, if you provide it, is correct.

AJAX :: Modalpopupextender And Update Panel - Disable Controls?

Jan 25, 2010

I have a webpage that contains a ModalPopupExtender who's PopupControlID contains a panel wrapped in an update panel. The panel contains a RadioButtonList and I have subscribed to the SelectedIndexChanged event in which I am setting an OnClientClick event for a button also inside the panel and update panel. My problem is that when the postback fires the controls in the panel are still enabled, that is the user can click the button before it has had a chance to set the OnClientClick code. Other update panels on this page (unrelated to the ModalPopup) seem to disable to use of other controls while the postback is occurring. How can I make this work in my ModalPopupExtender?

Here is my code

It is a pretty simple example of its use, in that I have list box allowing the users to create a new row in a table.

However, when I click targetcontrol, the background changes to the expended modal background, but instead of being able to use the listbox, everything in the content panel is the same as the background and none of the controls on the panel are enabled. In other words, the entire page is loaded dimgray, including the updatearea.

AJAX :: AjaxToolkit:ModalPopupExtender To Show A Modal Window Panel

Feb 25, 2010

I use ajaxToolkit:ModalPopupExtender to show a modal window panel. The panel among other things contains a "Submit" button. I would like to call a code behind function on Submit. First I tried this:

[Code]....

But btnSubmitOnHold_Click() is never called. Then I replaced OnClick="btnSubmitOnHold_Click" with OnClientClick="SubmitPutOnHold" and added

<script type="text/javascript">
function SubmitPutOnHold()
{
alert('blah');
}
</script>

This alert also never shows up. Finally, I tried

<ajaxToolkit:ModalPopupExtender ID="OnHoldModalPopupExtender" runat="server" TargetControlID="btnPutOnHold" PopupControlID="pnlOnHold" BackgroundCssClass="modalBackground" DropShadow="true" OkControlID="btnSubmitOnHold" CancelControlID="btnCancelOnHold"

AJAX :: ModalPopupExtender / Instead Of Dissapear These Modal Panel It Appers On The Bottom Left Corner Of The Page?

Feb 15, 2010

I'm developing an ASP.NET application with C# and Visual Studio 2008 SP1. I'm using WebForms.

I have an ASPX page with two UpdatePanels, one on the left that holds a TreeView and other on the right where I load dynamically user controls.

On the left panel I also have buttons to load user controls on the right. I have a ModalPopupExtender in a button that show I div with radiobuttons to select a type. When I choose an option and click ok it do a postback to load dynamically a user control but instead of dissapear these modal panel it appers on the bottom left corner of the page.
