When I have a TextBox editing element for a cell in edit mode, pressing Tab causes the next cell to become current and enter edit mode. I am having difficulty achieving the same behavior for more complex controls, such as ComboBox (not RadComboBox). I know how to customize ComboBox key handling so that Tab will select an item and hide the dropdown. But no matter what I do, I can't get it to move to the next cell. Instead focus moves to some control outside of the RadGridView, even when the drop down was not open.

Hello ,
By Default rad chart shows y axis point as annotations .
Is there any way to show x axis points as annoattions?
Thanks for any help.....

One correction :I meant Point labels.

I need to group a property that does not implement IComparable. I'd expect it to simply do a ReferenceEquals. It's not. It's erroring.

I cannot alter the class being grouped without serious effort, it's a WCF Data Services entity (they do not implement IComparable).

Hi,

I'm using a TileView and have a RadHorizontalBulletGraph that I only display when the TileView item is in the maximized state. When I maximize an item, the bullet graph displays correctly, but when I go to minimize the item, I get a NullReferenceException. There's not much of a stack trace, but here it is:

   at System.Windows.StyleHelper.FindNameInTemplateContent(DependencyObject container, String childName, FrameworkTemplate frameworkTemplate)
   at System.Windows.TemplateNameScope.System.Windows.Markup.INameScope.FindName(String name)

Here's a simplified version of my XAML. Any ideas?

Hi there,

I have a dynamic collection which I bind to the tab control, however, I would also like to be able to enable / disable the tabs based on some criteria, however, I am unsure of what to  bind to so I Can disable tabbing to the control.

I followed your basic demo for binding to a collection please see code below

<Grid>
        <Grid.DataContext>
            <WpfApplication3:MainWindowViewModel/>
        </Grid.DataContext>
        <telerik:RadTabControl ItemsSource="{Binding People}" >
            <telerik:RadTabControl.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Name}"/>
                </DataTemplate>
               
            </telerik:RadTabControl.ItemTemplate>
            <telerik:RadTabControl.ContentTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Age}"/>
                </DataTemplate>
            </telerik:RadTabControl.ContentTemplate>
        </telerik:RadTabControl>
    </Grid>

Thanks

Hi there,

I am using RadScheduleView version 2011.2.920.40 with ViewModel style.

XAML:
AppointmentsSource="{Binding StaffAppointments}" ResourceTypesSource="{Binding StaffResourcesTypes}"

The appointments are not updated on the view when AppointmentsSource is updated. Unless I click on WeeklyView then back to TimelineView, and the appointments are updated on the UI.

I thought this problem has been addressed?

Please advise.

Hello,
I have a Hierarchy RadGridView that works fine.

But there are 2 things I can'y achieve :
1. There can't be more than one row selected => if for example a user selects a row in the child Grid, no other row in the parent Grid must be selected. The same if the user selects a row in the parent Grid....
2. I want to retrieve the ID of the selected Row. It works if the user selects a row in the parent Grid, but not if the user selectd a row in th child Grid. In the SelectionChanged event, I cast e to GridViewDataControl, to be able to test ParentRow, but it's not working...

Thanks a lot for your help.

I'm currently evaluating the GridView control for a project and am trying to determine if it supports a feature I would like to have. I've searched for this and found nothing, but I'm not sure if there's a common name for the feature I'm unaware of.

What I would like is the ability to show the editor template for a cell on a certain trigger, but without the row/cell entering edit mode; it'd be a sort of 'preview edit' mode. Then, when the control gains focus it would enter 'true' edit mode.

This might make more sense in context. Say I have a column displaying dates, and the editor I want to use is a standard .NET DatePicker. To edit this value I would like it to work like this: when I mouse-over a cell in that column, the editor template appears for that cell. Then, I can click into the editor textbox or click on the button that launches the popup; either of these would enter edit mode. This would allow me to edit the value with one fewer click than I'm currently able to.

Is this supported and I'm missing it, or is it possible to write myself, or just completely unsupported? Thanks.

Hi telerik,

I'd like to write code that dynamically binds the Header to different properties on the DataContext depending on a bool.
I've found below code, but 'Header' is not the object to use in code - can you help me?

Thanks,

Hi,

I have used the below code to make the parent and child gird (self reference) column with as same.

this.binder = new ColumnWidthBinder(this.RadGridView1);

if (

 

 

dataControl.ParentOfType<RadGridView>() != null)
{
for(int i = 0; i < dataControl.Columns.Count; i++)
{
this.binder.RegisterColumn(dataControl.Columns[i], i);
}
}

all the column widths of parent and child coming correctly. the self reference hierarchy is also find but its like all left aligned. If I want to maintain the width as same and also the child items should indent from the parent (tree view hierarchy), what I have to do?

Any help appreciated?

Thanks,
Ramasamy
