GridView - Rowheader

I figured how to customize the column header.

GridColumn column = new GridColumn();

if (column.ControlObject is Eto.Wpf.Forms.Cells.CustomCellHandler.Column header)
{
    // Add to header whatever control you want  
    // Wpf - Windows only
    AFGridViewHeader _header = new AFGridViewHeader();
    header.Header = _header;
}

I am still having problems to get a rowheader.

Currently I am doing the following. When the Eto.Forms.GridView is constructed I am registering the LoadingRow event for the ControlObject:

if (this.ControlObject is Eto.Wpf.Forms.Controls.EtoDataGrid dataGrid)
{
    dataGrid.RowHeaderWidth = 20;
    dataGrid.LoadingRow += new EventHandler<System.Windows.Controls.DataGridRowEventArgs>(this.OnLoadingRow);
}

And handling the event:

private void OnLoadingRow(object sender, System.Windows.Controls.DataGridRowEventArgs e)
{
    e.Row.Header = (e.Row.GetIndex() + 1).ToString();
}

Nothing is showing up. Any help would be much appreciated.

@curtisw Could you have a look at this if there is any time available.

Hey @Christian_Hartz,

You have to set the DataGrid.HeadersVisibility property, something like this:

if (this.ControlObject is Eto.Wpf.Forms.Controls.EtoDataGrid dataGrid)
{
    dataGrid.RowHeaderWidth = 20;
    dataGrid.HeadersVisibility = System.Windows.Controls.DataGridHeadersVisibility.All;
    dataGrid.LoadingRow += this.OnLoadingRow;
}

Hope this helps!

Maybe one more thing to add here. To get the rowheaderwidth set to auto you have to set the double value to double.NaN.

if (this.ControlObject is Eto.Wpf.Forms.Controls.EtoDataGrid dataGrid)
{
    dataGrid.RowHeaderWidth = double.NaN;
    dataGrid.HeadersVisibility = System.Windows.Controls.DataGridHeadersVisibility.All;
    dataGrid.EnableRowVirtualization = true;
    dataGrid.LoadingRow += new EventHandler<System.Windows.Controls.DataGridRowEventArgs>(this.OnLoadingRow);
}

DataGrid.RowHeaderWidth Property
