how to set focus to particular cell of WPF toolkit datagrid

Question

I am using WPF toolkit provided DataGrid control to display product list along with its OpenStock, Description etc. In this DataGrid i have set OpenStock column to editable

Answer 1

You need to set the current cell to the one you want edited and then call BeginEdit in your Loaded handler:

dataGrid1.CurrentCell = new DataGridCellInfo(
    dataGrid1.Items[0], dataGrid1.Columns[3]);
dataGrid1.BeginEdit();

If you give your DataGridTextColumn a name in XAML you can use that name rather than Columns[3].

Answer 2

Use this code to move the scroll view to a specific cell:

dgv.ScrollIntoView(dgv.Items[row], dgv.Columns[col]);

Answer 3

I have datagrid with TextBox in DataTemplate of DataGridTemplateColumn. Also i am using Enter instead of Tab to focus TextBox

private void DataGrid_PreviewKeyDown(object sender, KeyEventArgs e)
{
    if (e.Key == Key.Enter)
    {
        e.Handled = true;
        var TabKey = new KeyEventArgs(e.KeyboardDevice, e.InputSource, e.Timestamp, Key.Tab);
        TabKey.RoutedEvent = Keyboard.KeyDownEvent;
        InputManager.Current.ProcessInput(TabKey);
    }
}

I solve focus problem with combination of this code:

dataGrid.Focus();
//In case of more columns
//dataGrid.CurrentCell = new DataGridCellInfo(dataGrid.Items[0], dataGrid.Columns[1]);
dataGrid.BeginEdit();
(Keyboard.FocusedElement as UIElement).MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));

Answer 4

This worked for me:

DataGridCellInfo dataGridCellInfo = new DataGridCellInfo(dataGrid1.Items[sampleRowIndex], dataGrid1.Columns[sampleColumnIndex]);
dataGrid1.SelectedCells.Clear();
dataGrid1.SelectedCells.Add(dataGridCellInfo);

This will select the cell you want to put the focus on.

A DataGridCellInfo object provides information about a cell and the data item that is associated with the cell. It is used instead of a reference to the actual DataGridCell object when the DataGrid control gets a cell, for example in the CurrentCell or SelectedCells properties. Check here for more info.

Use below function, it will work.

private void SetFocusOnGrid(DataGrid grid, int index)
{
    grid.ScrollIntoView(grid.Items.GetItemAt(index));
    grid.SelectionMode = DataGridSelectionMode.Single;
    grid.SelectionUnit = DataGridSelectionUnit.FullRow;
    grid.SelectedIndex = index;

    DataGridRow row = (DataGridRow)grid.ItemContainerGenerator.ContainerFromIndex(index);
    row.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
}
