programmically open GridRowDetails

[lina fetisova]

Good day!
Please, can you tell me how can I programmically open GridRowDetails in a particular row?

[Vlad]

Hello,

 If you set RowDetailsVisibilityMode="VisibleWhenSelected" you can simply select desired grid item to achieve your goal. For example:

RadGridView1.SelectedItem = RadGridView1.Items[10];

If the item is out of view you need to use ScrollIntoView/ScrollIntoViewAsync to scroll to this item!

All the best,

thank you, Vlad, but what should I do if my RowDetails opens when I click to plus in such a column:
<telerikGridView:GridViewToggleRowDetailsColumn CellStyle="{StaticResource GridViewToggleButtonColumnStyle}" />
?

[Vlad]

Hello,

 In this case you need to use ScrollIntoView/ScrollIntoViewAsync, ItemContainerGenerator to the GridViewRow and set DetailsVisibility.

Kind regards,

Vlad, thank you!
but how can I programmically open GridRowDetails if I have such a three-tiered GridView:

<telerikGridView:RadGridView>
    <telerikGridView:RadGridView.ChildTableDefinitions>               
                <telerikGridView:GridViewTableDefinition>
                    <telerikGridView:GridViewTableDefinition.Relation>
                        <telerikData:PropertyRelation ParentPropertyName="WorkPlaces" />
                    </telerikGridView:GridViewTableDefinition.Relation>
                </telerikGridView:GridViewTableDefinition>                    
            </telerikGridView:RadGridView.ChildTableDefinitions>
            
            <telerikGridView:RadGridView.HierarchyChildTemplate>
                <DataTemplate>
                    <telerikGridView:RadGridView ItemsSource="{Binding WorkPlaces}" >
                        <telerikGridView:RadGridView.ChildTableDefinitions>
                            <telerikGridView:GridViewTableDefinition>
                                <telerikGridView:GridViewTableDefinition.Relation>
                                    <telerikData:PropertyRelation ParentPropertyName="Licenses" />
                                </telerikGridView:GridViewTableDefinition.Relation>
                            </telerikGridView:GridViewTableDefinition>
                        </telerikGridView:RadGridView.ChildTableDefinitions>

                        <telerikGridView:RadGridView.HierarchyChildTemplate>
                            <DataTemplate>
                                <telerikGridView:RadGridView
                                    ItemsSource="{Binding Licenses}" >
                                </telerikGridView:RadGridView>
                    </telerikGridView:RadGridView>
</telerikGridView:RadGridView>

Hello ,

 You are using hierarchy - not row details. To achieve your goal you can use ExpandAllHierarchyItems() method. This thread can help. 

Sincerely yours,

Vlad, but if I want to Expand only one, exactly one item - what can I do?
I have not foud a lot of information about ExpandHierarchyItem property of GridView? How can I use it, please, can you tell me?

[Vlad]

Hi,

 You can use it like this:

RadGridView1.ExpandHierarchyItem(RadGridView1.Items[0]);

This will expand hierarchy for the first data item. 

All the best,
