How to set the cell focus in WPF

Question

Hi,

  Iam showing popup while clicking the cell of the grid.so while closing the popup the focus is not set to that cell.

the issue is, iam setting the button inside the DataTemplate and  the popup click event  is handled by this button .

the button will be a transparent.so while clicking the cell which has a button the focus will be set to that button not to the cell

how can i set focus to the cell.

  <c:Column CellStyle="{StaticResource GridCommentStyle}"  x:Name="Comments" Binding="{Binding Comment}" ColumnName="PopUpComments" Header="Comments" MinWidth="100" IsReadOnly="True"  AllowResizing="False" Width="2*" >
                    <c:Column.CellTemplate>
                        <DataTemplate>
                            <Button Height="20"  Focusable="True" Content="{Binding Comment}" Style="{StaticResource TransparentButton}" Click="PopupClick" />
                        </DataTemplate>
                    </c:Column.CellTemplate>

Use this code:

int index = 11;
myDataGrid.SelectedItem = myDataGrid.Items[index];
myDataGrid.ScrollIntoView(myDataGrid.Items[index]);
DataGridRow dgrow = (DataGridRow)myDataGrid.ItemContainerGenerator.ContainerFromItem(myDataGrid.Items[index]);
dgrow.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));

Many thanks Siva/Annabella

    Your post was helpful .

what i need is to set the focus to the cell when the button is clicked  through Xaml .hope you are clear.

here button is transparent so when we click on button inside the cell the focus actually goes to the button .not to the cell.

Hi sajithtgs,

Thank you for your reply and sorry for my delay reply due.

I thinking what you said for a long time and I think first you button is there in the datagrid cell, right? Event thoug it is transparent, but it is exist, and you need to click on it also, so how can we click on button and focus not on it? What we can do is to set the focus to cell after we click on button, right? And then we can change the focus in xaml also. So to set focus on cell in code is the way to go.

Hope what I say is clear.

And if you have any concern, please feel free to let me know.

Have a nice day.

You should do in the below style:

  <c:Column CellStyle="{StaticResource GridCommentStyle}" 
Focusable="{Binding IsFocused}"
 x:Name="Comments" Binding="{Binding Comment}" ColumnName="PopUpComments" Header="Comments" MinWidth="100" IsReadOnly="True"  AllowResizing="False" Width="2*" >
                    <c:Column.CellTemplate>
                        <DataTemplate>
                            <Button Height="20"   Content="{Binding Comment}" Style="{StaticResource TransparentButton}" Click="PopupClick" />
                        </DataTemplate>
                    </c:Column.CellTemplate>

while closing the popup...

((this.Parent).Content as TestViewModel).IsFocused = true

This solves your problem...
