Hi,

I wanted to create a usercontrol in WPF using a gridview and two buttons and wanted to use this usercontrol in another win form.

I have tried many ways to bind the usercontrol with some data. I am not able to achieve the same.

Please help me with some sample project will be highly appreciated.

Thanks!

Vaithi.

And If I want to define the columns (AutoGenerateColumns="False") ?? How do I do? It's possible?

You don't understanding! :)

I'm developing an user control. It is composed RadGridView and RadDataPager. In code behind, I create a property called 'Columns' of type GridViewColumnsCollection, for I set the columns in the window.

In the Window, I'm put my user control and works. But, If the window has 2 or more UserControl's, all the columns stays in the first User control, and the anothers grid's has no columns.

Code of the first user control in window:

<userControls:DataGridNotas x:Name="dtgOne" Height="120" Width="775"
SelectedItem="{Binding Path=MySelectedObject, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"
ListaBinding="{Binding Path=MySource, UpdateSourceTrigger=PropertyChanged}">
    <userControls:DataGridNotas.Columns>
            <telerik:GridViewDataColumn DataMemberBinding="{Binding Column1}" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Column2}" />
        </userControls:DataGridNotas.Columns>
</userControls:DataGridNotas>

This code is second user control in the Window

<userControls:DataGridNotas x:Name="dtgTwo" SelectedItem="{Binding Path=MySelectedObject2, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"
 ListaBinding="{Binding Path=MySource2, UpdateSourceTrigger=PropertyChanged}">
    <userControls:DataGridNotas.Colunas>
            <telerik:GridViewDataColumn DataMemberBinding="{Binding Column3}" Width="220" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Column4}" Width="220" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Column5}" Width="170" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Column6}" Width="200" />
         </userControls:DataGridNotas.Colunas>
</userControls:DataGridNotas>

  • So, the columns stays only in dtgOne and the dtgTwo has no column.


  • the Dependency Property in User control:


public static readonly DependencyProperty ColumnsProperty =
       DependencyProperty.Register("Columns", typeof(GridViewColumnCollection), typeof(DataGridNotas),
       new UIPropertyMetadata(new GridViewColumnCollection()));
[Bindable(true, BindingDirection.TwoWay)]
public GridViewColumnCollection Columns
{
    get { return (GridViewColumnCollection)GetValue(ColumnsProperty); }
        set { SetValue(ColumnsProperty, value); }
}
Sorry the bad english =/

Hello Diego,

You will have to initialize your columns collection in the constructor of your UserControl. Having its default value to a new GridViewColumnCollection in the dependency property metadata will make this collection shared between all the instances of your control. So you should make the default value null in the metadata and initialize it in the constructor to a new instance of GridViewColumnCollection.

You can also check this blog post which explains the problem you are facing.

Sincerely yours,
