I am creating tabs on the fly and need to be able to apply a theme to the actual RadTabItem.

I have tried the following with no success:
1) tab1.SetValue(Telerik.Windows.Controls.StyleManager.ThemeProperty, new VistaTheme());
2) Telerik.Windows.Controls.StyleManager.SetTheme(tab1, new VistaTheme());

tab1 is the tab I created:
RadTabItem tab1 = new RadTabItem();

Also, I cannot apply the theme to an existing tab (within the actual XAML) dynamically either.  If a RadTabItem exists with name "tab2" on the xaml form and I try and go and programatically apply a theme somewhere in the code it does not apply at all...

Any help with this would be great.  I really need to be able to apply themes on the fly to dynamically created telerik objects.

Thanks

 

Hy
How can I make the width of the grid to be strech on all window width?
Thanks

If a I create a simple form with just a RadGridView control:

Working with: Version 2009.1.526.35

Trying to set SelectedItem.
Code:

<telerik:RadGridView AutoGenerateColumns="False"
                             SelectedItem="{Binding Path=Entity, Mode=TwoWay}" IsReadOnly="False"
            ItemsSource="{Binding Path=Entities}"

In my constructor of my model I create a instance of Entity (Selected) and a List of Entities(ItemSource).

When I run, I get a Object Reference not Set... exception.
The same code works fine with a ListBox.

Hy
I want to add a Radio button column to my grid
I used the follwing code
how can I let only one radio button to be select
(a kind of a radio button group)
Thanks

Hello guys,
I've rebuilded the First Look Example with ChildTemplate, foto... etc.
Now my problem ist, that whenever I group by a column by dragging it into the header, only the first and the last record's childtemplate show up, when clicking the plus (+). When I click the plus of other records, the plus only changes to a minus and nothing happens. But when I cancel grouping this records, the record's childTemplates are expanded and shown. It looks like they are expanded in the background but cannot be shown in the grouped grid.

I'm using following methods seen in one of your examples. The first I'm using to have default collapsed grouping and the second to change selected row on first click (needs your sample class DependencyObjectExtensions.cs).


Is possibly here something going wrong?


Any help would be appreciated

Hi,

I'm having a problem with the GridView control on a client's machine. When I or my colleagues compile and run it everything goes right. However, when we deploy on a client's machine we get an error message saying "Cannot add content of type 'Telerik.Windows.Controls.GridViewDataColumn' to an object of type 'Telerik.Windows.Controls.GridViewColumnCollection'. Error at object 'Telerik.Windows.Controls.GridViewDataColumn' in markup file 'CowculationsWindows;component/useradmin.xaml' Line 57 Position 18."

This is the code:

<telerik:RadGridView Margin="15,66,9,46" Name="rgvUsers" AutoGenerateColumns="False" AddingNewDataItem="rgvUsers_AddingNewDataItem" ValidationMode="Row" AutoGenerateHierarchyFromDataSet="True" ColumnsWidthMode="Auto">   
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="Full Name" UniqueName="UserFullName" Header="Full Name"/>
                <telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="User Name" UniqueName="UserName" Header="User Name"/>
                <telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="Password" UniqueName="Password"/>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>

The particular line where the error happens is this:

<telerik:GridViewDataColumn DataType="{x:Null}" HeaderText="Full Name" UniqueName="UserFullName" Header="Full Name"/>

The GridView uses hierarchy, so that might be an issue.

Please help.

Hello,

I know how to create a combobox column and fill it with value, however

each combobox cell in the column does not show the drop down arrow, unless

the user clicks on the cell.

I tries using a combobox template on the column and visually it works, however when I do so

the combobox's possible values are not displayed in its drop down.

Hope you can assist.

After populating RadGridView with AutoGenerateColumns = true i try to change the column header text:

RGVBBoxRecords.Columns[idx].HeaderText = headerstr[idx];
or
RGVBBoxRecords.Columns[idx].Header = headerstr[idx];

but nothing changes.

How to do it?

 

In my project I want to use a "lookup" gridviewcomboboxcolumn in the radgridview. I don't  make use of  foreign key id-values, but entity framework associations instead. Is this possible and how should this be done?

Thanks,
Thomas.
