GGC dynamically setting datasource for GridListControl CellType

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.

Thanks, that worked. >Hi Chris, > >Try setting the data source in the gridGroupingControl1_TableControlCurrentCellActivated event handler to see if that helps.
