Select and FocusFirst Row

[VS]

Hi,

Is there a way to select and focus first row in grid at design time. I am using MVVM pattern. Since i cant get access to the grid from ViewModel and also dont want to write any code in codebehind, is it possible to do this at design time in View.
When i give SelectedIndex="0", it selects the fist row, but the focus is not there.

Any help is much appreciated.

Thanks

Hello Sujith,

You can bind the grid SelectedItem to a property of your model:

SelectedItem="{Binding YourProperty, Mode=TwoWay}"

You can do the same with CurrentItem.

Hi,

I didnt get the property part..what property should i use for this?
i just need to focus the first row when the form is loaded, so that users can use arrow keys to move down or up the rows.

When i do as below in the window

FocusManager.FocusedElement

 

="{Binding ElementName=myDataGrid}"
and put selectedindex="0" in the grid, the first row is selected and the grid is having focus and as a result, if i use down and up arrow keys, am able to move around the rows..
But my grid is in a usercontrol. The First row is selected and the grid is having focus but when using arrow keys, rows selections are not changed.

Any help is appreciated.

Hi Sujith,

It seems some other element is taking the focus out of the grid. Can you do the following: in your UserControl with the grid you can subscribe to the Loaded event. In the event handler you can use the following code:

this.Dispatcher.BeginInvoke((Action)() => this.MyGridView.Focus());

This should focus the grid view so that the keyboard navigation should work as expected.

Hi Stefan,

I can't use the Loaded event of the user control, since am using MVVM Pattern.

Any other solution? Am stuck with this problem.

Hi Sujith,

You can create an attached behavior that implements this behavior. This way you will not break the MVVM paradigm and isolated this code in the behavior.
