RadAutoCompleBox in GridViewDataColumn

[ali]

I have a GridViewDataColumn, in the first column is an AutoCompleteBox for searching names in a ObservablceCollection.

I have build the RadGridView with AutoCompleteBox like this:

 

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Width="*" IsReadOnly="False">
     <telerik:GridViewDataColumn.CellTemplate>
      <DataTemplate DataType="{x:Type detailViews:MyViewModel}">
       <Grid>
        <Grid.ColumnDefinitions>
         <ColumnDefinition Width="*"/>
         <ColumnDefinition Width="Auto"/>
        </Grid.ColumnDefinitions>
        <telerik:RadAutoCompleteBox DisplayMemberPath="Name"
                                    TextSearchMode="Contains"
               WatermarkContent="Suche..."
               AutoCompleteMode="Suggest"
               SelectionMode="Single"
                                    ItemsSource="{Binding Project.Names, RelativeSource={RelativeSource AncestorType=telerik:RadGridView}}"  />
        <telerik:RadButton Grid.Column="1" HorizontalAlignment="Right" Style="{StaticResource RadImageButton}" ToolTip="Search"
                Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=UserControl}, Path=DataContext.SearchFromDatabaseCommand}"
                CommandParameter="{Binding Path=.}">
         <Image Grid.Column="1" Source="{framework:ApplicationImage image}" Width="16" Height="16" />
        </telerik:RadButton>
       </Grid>
      </DataTemplate>
     </telerik:GridViewDataColumn.CellTemplate>
    </telerik:GridViewDataColumn>

 

My Problem is that the items of ObservableCollection not binded in autocompletebox. Is it possible with my type of implemetation of the AutoCompleteBox in the GridViewDataColumn?

Hello Ali,

Thank you for the provided code snippet. 

What I would suggest you is to place the RadAutoCompleteBox in the CellEditTemplate and bind the SelectedItem property of the RadAutoCompleteBox. I have created a sample project which demonstrates how you can sync the selected item and bind the ItemsSource of the RadAutoCompleteBox control inside the cell. 

Hope this project will be helpful.

How to get AutoCompleteBox items source to be data from one radgridview column ? Like autocomplete in Excel ?

Hello Nebojsa,

Such behavior is not supported out of the box. Still, you can try to achieve it using custom code. You can subscribe to the CellEditEnded event of the RadGridView and create custom code that populates the collection if the search text does not exist inside. I have modified my project to demonstrate what I have in mind. You can find it attached to this reply. 

Keep in mind that this is a custom solution and may not work in all cases. But I think is a good starting point to achieve your final behavior.
