Additional useful features

A customer is asking me if it's possible to do the following:

Entering time directly in the box, but filtering possible value as 00-23 for hours and 00:59 for minutes
Allowing maximum of 4 characters. I.e. 2359
Automatically SelectAll content of the input box on focus

Kind regards

IsTabStop false ignored on InputBox

I need to skip the inputBox focus on Tab in order to speed up data entry through keyboard, but even if we set IsTabStop property to false on the DatePicker, the InputBox on its left is still getting focus on Tab, is it possible to change this behaviour ?

Thanks and regards,

Ivan

Adding value to cell in readonly column in grid associated with dataset

FYI,

The first column of my grid is readonly. I needed to programmatically add a value to a cell in this column. This is how to do it:

<data table>.Columns[<column index>].ReadOnly = false;

<data table>.Rows[<row index>][<column index>] = <value>;

<data table>.Columns[<column index>].ReadOnly = false;

column index is 0 for me.

WPF - close teleric tabItem.

Hello, I organiza my windows like tabItems in tab controls. when i click on menu item:

                            private void PaieskaTab_Click(object sender, Telerik.Windows.RadRoutedEventArgs e)         
                    {         
                        RadTabItem tabItem = new RadTabItem();         
                        ListTemplate lst = new ListTemplate();         
                        lst.tabWindow = tabItem;         
                        tabItem.Content = lst;         
                        tabItem.Header = "Paieskos langas";         
                        tabItem.Name = "tabPaieskosTestas";         
                        tabControlR.Items.Add(tabItem);         
                    }         

ListTemplate is a user control. In List template is a button "Close". Now when i click this button, i need that this tab,whitch contains this user control, would close. I try code from other forum in telerik:

                                var tabItem = tabWindow as RadTabItem;         
                     
                        var parentItemsControl = Telerik.Windows.Controls.ItemsControl.ItemsControlFromItemContainer(tabItem);         
                     
                        parentItemsControl.Items.Remove(tabItem);          

But his code shows error:

Error 23 The type or namespace name 'ItemsControl' does not exist in the namespace 'Telerik.Windows.Controls' (are you missing an assembly reference?) D:\!_Projects\Teleric_EmptyProject WPF\XSoftArt.WPFengine\XSoftArt.WPFengine\BaseClasses\ListTemplate.xaml.cs 1102 63 XSoftArt.WPFengine

Its this becouse that code is for Silverlight..?How i must change it to get working..?

ContextMenu on RadGridView

Hello,

I need a context menu on my radgrid view, but i need it to operate on the current data context of the cell (I.e. each operation on the context menu will be on the current context of the cell (or row).

I used this code:

<telerik:RadGridView.Resources>

</ContextMenu>

</telerik:RadGridView.Resources>

But i didn't know how to implement Update_Click to operate on the appropriate DataContext

Thanks,

Ofer
