Need help with ComboBox ItemTemplates

[fred williams]

So I’m using the directoryinfo class to obtain the filenames from a network share, and then display them into my radcombobox. Everything works fine, but what I’d like to do is create a checkbox next to all of the values in the combobox so the user can select multiple files.

When I do it without the itemtemplate, all the filenames display fine, but when I try to use them to add the checkbox, the checkboxes show up but the filenames don’t. Here’s what I have:

<telerik:RadComboBox ID="cboFiles" runat="server" AutoPostBack="true" Width="350px" OnItemDataBound="cboFilesDBound">
     <ItemTemplate>
         <asp:CheckBox ID="chkFile" runat="server" />
     </ItemTemplate>
 </telerik:RadComboBox>

What do I need to put next to the checkbox to get the filenames to display? Again, when I do this without the template the filenames show fine. I tried using databinder.eval with some custom attributes like the demo, but it didn't work.

Here's the codebehind:

protected void setDirectory(String path)
{
    RadComboBox cb = (RadComboBox)FindControl("cboFiles");

    DirectoryInfo di = new DirectoryInfo(path);
    FileInfo[] files = di.GetFiles();
    foreach (FileInfo f in files)
    {
        RadComboBoxItem item = new RadComboBoxItem(f.Name, f.Name);
        item.Attributes["displayName"] = f.Name;
        cboFiles.Items.Add(item);
    }

}

Hi fred williams,

You need to use data binding expressions inside the ItemTemplate definition to render the additional data as done in the first RadComboBox in this demo.

I hope this helps.

All the best,
