How to focus a particular UIElement inside DataTemplate after calling CurrentCell.BeginEdit() or when entering edit mode in WPF Grid?
When you use the GridTemplateColumn while entering edit mode, SfDataGrid cannot focus particular UIElement defined inside GridTemplateColumn.EditTemplate. This occurs, as you can load any control within the DataTemplate and it is not possible to focus the control loaded within the DataTemplate by default.
You can set focus to a UIElement inside GridTemplateColumn.EditTemplate by setting FocusManagerHelper.FocusedElement property to true or you can use the FocusManager.FocusedElement to focus the particular UIElement inside DataTemplate.
Consider the following example where you have GridTemplateColumn for “CustomerID”. When entering into edit mode, TextBox that is defined inside the GridTemplateColumn.EditTemplate is loaded as DataTemplate for the cells of the CustomerID column and TextBox does not get focused. You can set focus to the TextBox when entering edit mode, by setting the attached property “FocusManagerHelper.FocusedElement” to Textbox as true.
XAML
<syncfusion:SfDataGrid x:Name="grid"
AllowEditing="True"
AutoGenerateColumns="False"
ItemsSource="{Binding OrderList}"
LiveDataUpdateMode="AllowDataShaping"
ShowRowHeader="True">
<syncfusion:SfDataGrid.Columns>
<!-- grid template column is created here -->
<syncfusion:GridTemplateColumn HeaderText="Customer ID"
MappingName= "CustomerID">
<syncfusion:GridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock FontStyle="Italic"
FontWeight="SemiBold"
Padding="2,0"
Text="{Binding CustomerID}" />
</DataTemplate>
</syncfusion:GridTemplateColumn.CellTemplate>
<syncfusion:GridTemplateColumn.EditTemplate>
<DataTemplate>
<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<TextBox x:Name="textBox" FontStyle="Italic" FontWeight="SemiBold"
syncfusion:FocusManagerHelper.FocusedElement="True"
Text="{Binding CustomerID, Mode=TwoWay}" />
</Grid>
</DataTemplate>
</syncfusion:GridTemplateColumn.EditTemplate>
</syncfusion:GridTemplateColumn>
</syncfusion:SfDataGrid.Columns>
</syncfusion:SfDataGrid>Conclusion
