GridView With Checkbox Column. Client-side Script To Uncheck All Except Current Checkbox?
Jun 29, 2010I am dynamically binding a typed list to a GridView control.
The Grid View Control is in an asp.net page that is wrapped in an asp:UpdatePanel (Ajax).
The first column contains a checkbox control.
Only one checkbox may be checked in this column.
If the user checks a checkbox, all other checkbox must be unchecked.
I am trying to achieve this using client-side script without success.
In the handler for the GridView's RowDatabound event, have attempted to add an attribute to the CheckBox contained within the cell.

Jan 27, 2010I have an ASP.NET web form that has 6 checkbox. 1 checkbox is to call a Function to select all checkbox and show the message "You have selected" 6 "items" (in this case, 6 checkbox). If a user doesn't select the Select All checkbox, they can select or deselect other checkbox individually and the message will be "You have selected" # "items" I'm trying to do this in jQuery, but it's not working yet.

Web Forms :: Checkbox / Checkbox List Not Behaving?
Jan 14, 2010I am absoluetly confused. My web app has a checkbox list that my code is looking to see if the user checked it. Like I said, very simple stuff... Here's the code:
If (chkLaunch.Items(1).Selected) Then
Launch = 1
End If
The odd thing is that when it gets to this bit of code it just moves right past it like it wasn't checked. The same thing happens when I use a single checkbox (rather than a checkbox list). I've tried a bunch of different ways to make the code work but I'm left to the conclusion that I'm just not telling it to do this correctly. Either that or my project is messed up somehow.I say that my project is messed up because when I add an object to the page in Design mode, it doesn't write the source code. So when I save and close, all the modifications are mysteriously gone. This happens on multiple PC's...So, is the checkbox problem just me not doing something correctly or is my web project messed up?

View 5 RepliesJQuery :: Checkbox Click Event Problems When Using JQuery Safari Checkbox Plugin?
Nov 26, 2010my page are 1 checkbox and 1 hidden label and 1 hidden panel. With the help of forum member raghav_khunger I've managed to write the code which shows panel and label when checkBox is checked. I've also added the code which is checking on every page post back the status of checkbox and hide/show panel and label appropriately. This is working fine.However when I add jQuery Safari checkbox plugin [URL] problems appear.
Looks like the code which is handling click event is doing reverse thing: when panel and label should be hidden are shown. I can change this but then there would be problems because of the second part of the code which is checking checkbox on page load. So when I check the checkbox nothing happens. I must uncheck it and label and panel appears. But if panel is uncheck the label and panel would be hidden because on next page load (when user clicks button next).As I said before the same code is working fine and it's test in all browsers (IE,FF,O,S,C). Maybe there is problem with checkbox plugin since it's in beta version.

Telerik Grid With Checkbox - Checkbox Not Showing Up When The Grid Initially Paints?
Nov 22, 2010I have a telerik grid with a checkbox. I am using a client template. There is a .DataBinding Ajax call attached. When the grid initially comes up, instead of a checkbox, it has the id value as text.If I hit refresh, the ajax call gets executed and when it comes back the checkbox appears. Is there any way to force the ajax call to happen when the grid initially paints so that I have a checkbox and not text..
