change or filter a list in the event QueryCellStyleInfo (WinForms)

[Adrien Falconnet]

I want to change the datasource of a GridListControl (which is in a column of a grouping grid) in the event QueryCellStyleInfo.
This is the code below in the event QueryCellStyleInfo :

e.TableCellIdentity.Table.Engine.SourceListSet[stat.Code].List = selectStatus.ToList();
e.TableCellIdentity.Table.TableDescriptor.Relations[0].Name = "Name";
e.TableCellIdentity.Table.TableDescriptor.Relations[0].MappingName = "Code";
e.TableCellIdentity.Table.TableDescriptor.Relations[0].ChildTableName = stat.Code;

This code doesn't work. I can't update my list in the event QueryCellStyleInfo. There's no items in my list. Why ??

Hi,

Thank you for posting query to us.

Please see the following code that shows how to set datasource to the gridlist dropdown in GridGroupingControl in QueryCellStyleInfo event.

this.gridGroupingControl1.TableDescriptor.Columns["Col0"].Appearance.AnyRecordFieldCell.CellType = "GridListControl";

void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
if (e.TableCellIdentity.TableCellType == GridTableCellType.AlternateRecordFieldCell
|| e.TableCellIdentity.TableCellType == GridTableCellType.RecordFieldCell)
{
if (e.TableCellIdentity.Column != null && e.TableCellIdentity.Column.MappingName == "Col0")
{

e.Style.DataSource = GetTable1();
e.Style.DisplayMember = "ID";
e.Style.ValueMember = "Description";

}
}
}
