RadComboBox CellTemplate in RadGridGriew

[Andrei]

I have a RadGridView with a column that is RadComboBox:




<telerik:RadGridView x:Name="gridSelectedResources" Style="{StaticResource GridViewSelectedResources}"
                                         BeginningEdit="gridSelectedResources_BeginningEdit"
                                         RowEditEnded="gridSelectedResources_RowEditEnded"
                                         Deleted="gridSelectedResources_Deleted"
                                         EditTriggers="CellClick"
                                         IsReadOnly="{Binding CurrentRole.Editable,Converter={StaticResource ReverseBoolConverter}}">
<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn.CellEditTemplate>
                                    <DataTemplate>
                                        <telerik:RadComboBox
                                            Style="{StaticResource ComboBoxCellEditStyle}"
                                            Loaded="RadComboBox_Loaded"
                                            SelectionChanged="RadComboBox_SelectionChanged"
                                            DisplayMemberPath="Name"
                                            SelectedValuePath="Id"
                                            SelectedValue="{Binding CS.Id, Mode=TwoWay}"
                                            >
                                            <i:Interaction.Behaviors>
                                                <sharedBehaviors:ShowDescriptionBehavior ComboBoxWithDescriptionTemplate="{StaticResource NonEditableComboBoxWithDescription}"/>
<telerik:RadGridView.Columns>
                                            </i:Interaction.Behaviors>
                                        </telerik:RadComboBox>
                                    </DataTemplate>
                                </telerik:GridViewDataColumn.CellEditTemplate>
                            </telerik:GridViewDataColumn>
 </telerik:RadGridView.Columns>
                    </telerik:RadGridView>


Problem: how from tests select a item from RadComboBox?
I try to Cast, but it doesn't work, I try to FindAllByType<RadComboBox> => count is 0.

Do you have some solutions to solve this problem?

Hello Andrei,

Is this a Silverlight RadComboBox? If so, here's code against a sample Telerik demo page that gets a list of all RadComboBoxes and makes a selection from the first one:

Settings.Current.Web.EnableSilverlight = true;
Manager.LaunchNewBrowser();
ActiveBrowser.NavigateTo("http://demos.telerik.com/silverlight/#ComboBox/FirstLook");

SilverlightApp app = ActiveBrowser.SilverlightApps()[0];
Telerik.WebAii.Controls.Xaml.RadComboBox cb = app.Find.ByAutomationId<Telerik.WebAii.Controls.Xaml.RadComboBox>("TechnologySelection");
Assert.IsNotNull(cb);

IList<Telerik.WebAii.Controls.Xaml.RadComboBox> list = app.Find.AllByType<Telerik.WebAii.Controls.Xaml.RadComboBox>();
Log.WriteLine(list.Count.ToString());

cb.SelectItem("Silverlight", true);
System.Threading.Thread.Sleep(1000);

If you continue to have difficulty, can you point me to a public site that demonstrates the behavior along with a full code sample I can run directly?

Kind regards,

Yes, it;s a Telerik RadComboBox.
When RadComboBox isn't as CellTemplate => I know how access it and select items, but in my case this RadComboBox is in RadGridView cell template => and I can't find some solutions to get this RadComboBox and select some items.

Hello Andrei,

Perhaps the ComboBox isn't "active" until clicking or double clicking on the cell (or row). In the example below, I identify a specific row in the grid, double click it, then identify and make a selection from its RadComboBox. You may need to go further and identify a specific cell in the row as well.

Settings.Current.Web.EnableSilverlight = true;
Manager.LaunchNewBrowser();
ActiveBrowser.NavigateTo("http://demos.telerik.com/silverlight/#GridView/ComboBoxColumn");

SilverlightApp app = ActiveBrowser.SilverlightApps()[0];
RadGridView grid = app.Find.ByAutomationId<RadGridView>("RadGridView1");
Assert.IsNotNull(grid);

GridViewRow row = grid.Rows[2];
row.User.Click(MouseClickType.LeftDoubleClick);

Telerik.WebAii.Controls.Xaml.RadComboBox cb = row.Find.ByType<Telerik.WebAii.Controls.Xaml.RadComboBox>();
cb.SelectItem("Product6", true);
System.Threading.Thread.Sleep(1000);
