I want to be able to pick a specific cell in a Silverlight 3.0 DataGrid and put it into edit mode. I can use the VisualTreeManager to locate the cell. How do I switch to edit mode?
Each DataGridCell looks like this in the VisualTreeManager:
System.Windows.Controls.DataGridCell
System.Windows.Controls.Grid
System.Windows.Shapes.Rectangle
System.Windows.Controls.ContentPresenter
System.Windows.Controls.TextBlock
System.Windows.Shapes.Rectangle
System.Windows.Shapes.Rectangle
with the TextBlock containing the text I want to edit.
Update
Following @AnthonyWJones' suggestion, here's how I tried to do this using BeginEdit().
I wanted to keep it simple so I thought I'd pick a column in the first row. Even that proved beyond my SL knowledge! In the end, I get the first row by creating a field called firstRow to hold it:
private DataGridRow firstRow;
added a LoadingRow handler to the DataGrid:
LoadingRow="computersDataGrid_LoadingRow"
and
private void computersDataGrid_LoadingRow(object sender, DataGridRowEventArgs e)
{
if (this.firstRow == null)
this.firstRow = e.Row;
}
and then adding a button to the panel to trigger the edit:
private void Button_Click(object sender, RoutedEventArgs e)
{
this.dataGrid.SelectedItem = this.firstRow;
this.dataGrid.CurrentColumn = this.dataGrid.Columns[4];
this.dataGrid.BeginEdit();
}
I click the button and the correct cell is selected but it doesn't go into edit on the cell. It takes a manual click to achieve that.
