Web Forms :: Control Checkbox Selection From CheckBoxList Using Javascript?

Apr 19, 2010

I am binding a checkboxlist with a dataset (with these columns :
id,empname,resourceId,balanceId as columns) with datavaluefield as id and datatextfield as empname;

Now, i want to control the selection of the items. Say some thing like

1. "User should be allowed to check only say 5 items with same resourceId" using javascript

2. And in total he should select only 20 items (max 5 items for same resource id and max 15 items for the remaining)

How can we control this?

JQuery :: How To Get The Text Of Selected Checkbox From Checkboxlist Control

Aug 26, 2010

I have asp.net checkboxlist control that bounded to a data source so the number of items in the control are different from one to to another time.

Web Forms :: Which Checkbox (in A CheckboxList) Changed?

May 26, 2010

I have a rather short (~30 item) CheckboxList control and when it changes, I need to know which Checkbox changed.

I've got the CheckboxList set to AutoPostBack so I know only one Checkbox changed, but I don't know how to detect which one.

Unfortunately, the SelectedIndex property of the CheckboxList is useless. I'm sniffing around checking the ViewState, but I'm not sure if that'll work or how I go about that.

Checkboxlist Not Retaining Selection After Postback In IE?

Aug 1, 2010

Platform: ASP.Net 2.0 I have multiple checkboxlist controls on a webpage. Along with that i have the same number of buttons on that page. Initially all the checkboxlist controls are hidden. When user clicks on a button, corresponding checkboxlist controls gets visible making others hidden and allows user to select the options.

On postback, if user clicks on the same button again, the corresponding checkboxlist gets visible but the item selection is not retained. However, this happens only in IE. This works fine in FireFox. I am using JQuery to toggle the visibility of checkboxlist.I guess the problem is because i am toggling the visibility of checkboxlist which IE doesnt seem to like. What is the solution to this problem?

Jan 24, 2016

I have dynamically popute the data in Dropdownlist(Countries) and the On selected index event of Dropdownlist there is noeed to bind /populate the Checkbox list from database depending on the selections made from the Dropdownlist.

<!DOCTYPE html>
