GLC Alternate Colors

[KMS]

I have a GGC, with a GridlistControl in one of the TableDescriptor cells. I''m using the following to do alternate colors:

GridTableCellStyleInfo style (GridTableCellStyleInfo) e.Inner.Style;
if (style.TableCellIdentity.TableCellType == GridTableCellType.RecordFieldCell || style.TableCellIdentity.TableCellType == GridTableCellType.AlternateRecordFieldCell)
{
if (e.Inner.RowIndex > 1 && (e.Inner.RowIndex % 2) == 0)
e.Inner.Style.BackColor = System.Drawing.Color.FromArgb(148, 207, 247);
else
e.Inner.Style.BackColor = System.Drawing.Color.FromArgb(255, 255, 255);
}

The GLC however, is all one color based on the current cell color.

Thanks

Your code sets the colors in the GridGroupingControl. It does not try to set the colors in the embedded GridListControl of a cell. To do this, you can subscribe to the PrepareViwStyleInfo event in the Grid property of teh embedded GridListControl, and use that event to provide alternating colors to the dropdown. Here is code that you can use to subscribe to the event.

GridDropDownGridListControlCellRenderer cr = this.gridGroupingControl1.TableControl.CellRenderers["GridListControl"] as GridDropDownGridListControlCellRenderer;
cr.ListControlPart.Grid.PrepareViewStyleInfo += new GridPrepareViewStyleInfoEventHandler(Grid_PrepareViewStyleInfo);

Hi Clay, I have added the code in the form load, but for some reason the event is not getting invoked. My Grid_PrepareViewStyleInfo function is not getting called when my GLC drops down. >Your code sets the colors in the GridGroupingControl.

You are using the GridListControl from a nested table, not the parent table. So, you will have to get the TableControl diferently. The "ChildToGrandChild" used below is the name of the relation that ends at this TableControl.

GridDropDownGridListControlCellRenderer cr = this.gridGroupingControl1.GetTableControl("ChildToGrandChild").CellRenderers["GridListControl"] as GridDropDownGridListControlCellRenderer;
			cr.ListControlPart.Grid.PrepareViewStyleInfo += new GridPrepareViewStyleInfoEventHandler(Grid_PrepareViewStyleInfo);

Thanks fo rthe response Clay,

I''m not sure what''s going on at this point. As soon as the code

GridDropDownGridListControlCellRenderer cr = this.plannedOrdersGridGroupingControl.GetTableControl("ChildToGrandChild").CellRenderers["GridListControl"] as GridDropDownGridListControlCellRenderer;

is executed, I get the old: Object reference not set to an instance of an object error.

Here is a sample with that code working.

Check to make sure you are using the proper string ("ChildToGrandChild") in the GetTableControl call. It should be the relation name.

I''m getting a "page not found" error on the sample zip file.
