Hi There
I'm trying to expand Child nodes of a RadTreeNode using ExpandChildNode() method and it's not working, am I missing something?
Or is this the right method to use?

foreach (DataSetStaffs.TeachRow rwTeach in lstTeach)

foreach (RadTreeNode rndDegree in rtvCourses.Nodes)

foreach (RadTreeNode rndCourse in rndDegree.Nodes)

if (rndCourse.Value == rwTeach.CourseID.ToString())

{

rndCourse.Checked = true;

rndDegree.ExpandChildNodes();

}

Please hlelp on this issue , It is very urgent .
I need to do goup by (By Drag and drop ) . When I am using GridBoundColumn It is working fine. but when i am using

GridTemplateColumn with HeaderTemplate . I am not able to do drag and drop columns to do groupby and sorting the column also.I am not binding values in the header template . I am just arranging with a label with text value set directly and image.

Whether Is it mandatroy that i must bind some thing to the label in header template. I couldnt understand why it is not working .

Here is code i am using

<telerik:GridTemplateColumn GroupByExpression="CloseOutType" DataField="CloseOutType" SortExpression="CloseOutType" HeaderStyle-CssClass="xmediumcolsize" >

<HeaderTemplate>

<asp:Image ID="imgCloseOutType" ImageUrl="~/Images/closeout_type.png" runat="server" />

<asp:Label ID="lblheaderCloseOutType" runat="server" Text="Interim/Workbook" ></asp:Label>

<%-- <asp:HiddenField ID="HiddenField1" Value='<%# eval("CloseOutType") %>' runat="server" />--%>

Over riding double click to insert new appointment

Hi,

I have a custom form used to create new meetings and have disabled AllowInsert so meetings cannot be created using the built in form.
How can I make it so if a user double clicks in an empty time slot, it will show my form to create a new meeting?

Thanks

Insert into DB on Click event

Hello!

At this moment I have 3 RadListBoxes side by side and an Button like the code bellow.
The purpose is to select items on the 3 listBoxes and click on the "assign" button, and select those select items on a Table on my database.

I have already my 3 ListBoxes populating data using DataBind().
Can you show me an example of doing that with MVP and Entity Framework? All the 3 list boxes have multiple selection, and i have already the edmx created for my database and the class for that table, i want to insert data named (UsersAssign).
