GGC dynamically setting datasource for GridListControl CellType

[Chris Victory]

In my GGC I have a column that I want to display a GridListControl in utilizing a dynamic collection of data. I''m using the TableControlCurrentCellShowingDropDown to set the datasource but the control does not show when I click the dropdown even though the objects are populated. I dried this code with the dropdown and it works fine.

private void wgcAttributes_TableControlCurrentCellShowingDropDown( object sender, GridTableControlCurrentCellShowingDropDownEventArgs e )
{
selectedAttribute.selected = 1;

GridComboBoxCellRenderer cr = (GridComboBoxCellRenderer)e.TableControl.CurrentCell.Renderer;
cr.ListBoxPart.DataSource = selectedAttribute.AttributeValues;
cr.ListBoxPart.DisplayMember = ReportAttributeValue.FieldNames.Name;
cr.ListBoxPart.ValueMember = ReportAttributeValue.FieldNames.Name;
}

However the code for the list control will not display the dropdown list control. Here is the code.

private void wgcFiltering_TableControlCurrentCellShowingDropDown( object sender, GridTableControlCurrentCellShowingDropDownEventArgs e )
{
selectedFilter.selected = 1;

GridDropDownGridListControlCellRenderer cr = (GridDropDownGridListControlCellRenderer)e.TableControl.CurrentCell.Renderer;
cr.ListControlPart.DataSource = selectedFilter.FilterValues;
cr.ListControlPart.DisplayMember = ReportFilterValue.FieldNames.Name;
cr.ListControlPart.ValueMember = ReportFilterValue.FieldNames.Value;
}

When I add a regular GridListControl to the form and set it''s datasource property it works fine as well.

Am I missing something or should I try a different approach?

Hi Chris,

Try setting the data source in the gridGroupingControl1_TableControlCurrentCellActivated event handler to see if that helps. Below is a code snippet.

private void gridGroupingControl1_TableControlCurrentCellActivated(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlEventArgs e)
{
GridCurrentCell cc = this.gridGroupingControl1.TableControl.CurrentCell;

GridDropDownGridListControlCellRenderer cr = cc.Renderer as GridDropDownGridListControlCellRenderer;

cr.ListControlPart.DataSource = //set data source
...........
...........

}

}

Regards,
Calvin.
