Is there a simple way, by setting a property, that the items that are checked that show up in the checked list area, (not in the drop down list) stay sorted as they are sorted in the Drop Down and not sort based on the order they checked them in the list? 

 

If not, what would be the best way to make this happen?

 

 

Thanks

This is how I populate my ListView:

 

List<Users> ListUsers = (List<Users>)FormData.Resp;
 
lv.Items.Clear();
 
foreach (var User in Users)
{
                    ListViewDataItem ListViewDataItem = new ListViewDataItem();
                    lv.Items.Add(ListViewDataItem);
 
                    ListViewDataItem[0] = User.ID.ToString();
                    ListViewDataItem[1] = User.BenutzerID;
                    ListViewDataItem[2] = User.Nachname;
                    ListViewDataItem[3] = User.Vorname;
                    ListViewDataItem[4] = User.EMailAdresse;
}

 

 

After selecting Items, the "Text" property of CurrentItem, SelectedItem or SelectedItems[0] is always empty. I tried also to get the Text by "lv.Items[lv.SelectedIndex].Text", but where is also the text property empty. But the SelectedIndex is correct.

Hi,

I`m new to Telerik, so please help!

I have a GridView with several columns of different types..Two of these column types are GridViewComboBoxColumn..

The content in the GridViewComboBoxColumn cell can be unique for each row. And the content in the GridViewComboBoxColumn cell depends on another cell. 
If I change the value in one cell, I want the GridViewComboBoxColumn cell to update automaticly when the editing ends.

How can I achieve this?

Please help!

Hello, 

I am relatively new here, and would need help with how i can set different ContextMenusStrip based on selected child template in my RadGridView.

I am using one GridView with four child templates and would want each of them to be assigned a different ContextMenuStrip to ease  the operations around the data in each template. So my barrier now is now to programatically check which template is currently selected (focused) and bind the ContextMenuStrip accordingly or at least disable some buttons in it based on desired output

 

Thanks in advance for looking into this

I've just updated to the latest release and am very happy with the improved PDF support over previous versions. I see there is still no support for comments, highlights or stamps though. Is there any way to enable these or will only be added in future versions. These are old PDF features so I am very surprised they are not yet included.

I have a very basic sample file demonstrating this.

Hello,

I'm trying to use RadTimePicker but i have a problem if a user selected a time, no way to clear the timepicker after a lot of search i found that this control has a clear button buildin, i made the button it visible and set it text once i run the application (Windows Application) it doesn't show at all.

I tried by code and by Edit UI Elements.

((Telerik.WinControls.UI.RadTextBoxElement)(RadTimePicker1.TimePickerElement.Children[2].Children[0])).ClearButton.Visibility = ElementVisibility.Visible;
((Telerik.WinControls.UI.RadTextBoxElement)(RadTimePicker1.TimePickerElement.Children[2].Children[0])).ClearButton.Text = "Clear";
((Telerik.WinControls.UI.RadTextBoxElement)(RadTimePicker1.TimePickerElement.Children[2].Children[0])).ShowClearButton = true;

 

Could you please advice.

Thank you

Hi, 

I have a simple grid with 1 field in the master template, and one field in the child template. I want to use the load on demand, the solution works fine without await/async:

 

 

Private Async Sub RadGridView1_RowSourceNeeded(sender As Object, e As GridViewRowSourceNeededEventArgs) Handles RadGridView1.RowSourceNeeded
      'Add 3 sub rows
       Dim row1 As GridViewRowInfo = e.Template.Rows.NewRow
       row1.Cells(0).Value = "Test 1"
       e.SourceCollection.Add(row1)
 
       Dim row2 As GridViewRowInfo = e.Template.Rows.NewRow
       row2.Cells(0).Value = "Test 2"
       e.SourceCollection.Add(row2)
 
       Dim row3 As GridViewRowInfo = e.Template.Rows.NewRow
       row3.Cells(0).Value = "Test 3"
       e.SourceCollection.Add(row3)
   End Sub

 

 

However, when I use await with the event, the parent row does not auto expand, and the behavior become weird when trying to select child row there is a lot of scrolling and flickering:

 

Private Async Sub RadGridView1_RowSourceNeededAsync(sender As Object, e As GridViewRowSourceNeededEventArgs) Handles RadGridView1.RowSourceNeeded
         
'Simulate Await
        Await Task.Delay(1000)
 
        Dim row1 As GridViewRowInfo = e.Template.Rows.NewRow
        row1.Cells(0).Value = "Test 1"
        e.SourceCollection.Add(row1)
 
        Dim row2 As GridViewRowInfo = e.Template.Rows.NewRow
        row2.Cells(0).Value = "Test 2"
        e.SourceCollection.Add(row2)
 
        Dim row3 As GridViewRowInfo = e.Template.Rows.NewRow
        row3.Cells(0).Value = "Test 3"
        e.SourceCollection.Add(row3)
    End Sub

 

Many Thanks

Sameh
