Get Grid Cell by mouse click

Question

I have a WPF Grid which is divided into 3 rows and 3 columns, i wasn\'t able to find a way of getting the row and column number of mouse click on the net, ohh and if it is p

Answer 1

I use something like this:

private void DataGrid1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
    {
        // Check if the user double-clicked a grid row and not something else
        if (e.OriginalSource == null) return;
        var row = ItemsControl.ContainerFromElement((DataGrid)sender, e.OriginalSource as DependencyObject) as DataGridRow;

        // If so, go ahead and do my thing
        if (row != null)
        {
            var Item = (CLASS_YOU_USE_TO_BIND)DataGrid1.Items[row.GetIndex()];
//Here you can work with Item, it is now the object of class you used in
//DataGrid.DataSource
        }
}

Answer 2

It's answered here: Ways to identify which cell was clicked on WPF Grid?

I've never used WPF Grid before, though using that link above as an example I think something like this should do it:

Add this to your Initialize method:

this.GridCtrl.MouseDown += new MouseButtonEventHandler(GridCtrl_MouseDown);

And add new method to handle the event:

private void GridCtrl_MouseDown(object sender, MouseButtonEventArgs e)
{
    if (sender != null)
    {
        Grid _grid = sender as Grid;
        int _row = (int)_grid.GetValue(Grid.RowProperty);
        int _column = (int)_grid.GetValue(Grid.ColumnProperty);
        MessageBox.Show(string.Format("Grid clicked at column {0}, row {1}", _column, _row));
    }
}

Answer 3

just try this

Grid.GetRow(NAME OF GRID)
Grid.GetColumn(NAME OF GRID)

Answer 4

Faced with the same problem I came up with this solution:

XAML:

<Grid Name="myGrid" Background="Transparent" PreviewMouseLeftButtonDown="OnPreviewMouseLeftButtonDown">

NOTE: The Grid has to be given a background to raise the mouse down event, see: How to get a Grid to raise MouseDown events when no UIElemets in cells clicked?

Code-behind:

private void OnPreviewMouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    if(e.ClickCount == 2) // for double-click, remove this condition if only want single click
    {
        var point = Mouse.GetPosition(myGrid);

        int row = 0;
        int col = 0;
        double accumulatedHeight = 0.0;
        double accumulatedWidth = 0.0;

        // calc row mouse was over
        foreach (var rowDefinition in myGrid.RowDefinitions)
        {
            accumulatedHeight += rowDefinition.ActualHeight;
            if (accumulatedHeight >= point.Y)
                break;
            row++;
        }

        // calc col mouse was over
        foreach (var columnDefinition in myGrid.ColumnDefinitions)
        {
            accumulatedWidth += columnDefinition.ActualWidth;
            if (accumulatedWidth >= point.X)
                break;
            col++;
        }

        // row and col now correspond Grid's RowDefinition and ColumnDefinition mouse was 
        // over when double clicked!
    }
}
