I have written this code but the RG_TYPE_SET is a boolean, so if it is true I want the tick boc to be selected.When I run this it only ever selects the last item in the list! Can more than one item be selected?
I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.

I am trying to get a drop down and a form view to work together. I've never used form views before. I also am using the entity framework to do everything. This is also my first time with it.
I want to be able to have a drop down, that is populate from the same data source as the form view. So far that works fine.
I then want to be able to change the drop down item, and it change the form view item that is displayed. I cannot figure out how to make this work.

chklbCourses.DataBind();
Now I want to add another item to checkboxlist which is price of each item that is coming from database. How can I attach third value "Price" to each item of checkboxlist. Do I need to add attribute or what to each item ?

View 6 RepliesI have a page with 5 seperate collections of checkboxes that are created according to entries in a database...i.e. the checkboxes ID values correspond to a selectable list from a database.
I also have a list of records which is a subset of the list of checkboxes and refers to those checkboxes within the list that have been checked (selected).

I've built the checkboxes in the view by passing the list via the model and using a for loop as so:

I've also passed the list of checkboxes that should be checked via the model. My problem now is initially how to populate those checkboxes that should be checked.

There is a bug in jQuery 1.4.2 that makes change event on select-element getting fired twice when using both DOM-event and a jQuery event, and this only on IE7/8.Here is the test code:
<html>
<head>
<script src="http://code.jquery.com/jquery-1.4.2.js" type="text/javascript"></script>[code].....
This causes alot of trouble for us in our application cause we use both ASP.NET-events mixed with jQuery and once you hook up a change event on any element every select (dropdown) gets this double firing problem.
I have a checkboxlist (cblTeamMates) with a sqldatasource (sqlTeamMates) that has 3 columns (ID, FullName and Status ). The datavaluefield and datatextfield for cblTeamMates is "FullName" and the 2 status values possible are "Available" and "Absent". How do I go about, in the page load event, checking all the names (FullName) whose Status is "Available"?
