Setting BackColor for each level

[Administrator]

Hi,

How can I set the different ‘BackColor’ for each level when using GDBG in a hierarchical view?

Based on the user action and data each ‘level’ will dynamically change the ‘BackColor’. I can’t do that at design time or at the time of form load. I have to do this runtime in response to a user action.

I understand that I need to do something like

level.RowStyle.BackColor = Color.Red;

But I don’t know how to get all the ‘levels’. Starting from ‘root’ to the last level.

Thanks,
Philip

Given a grid row index, you can get the level index for the row using:

GridBoundRecordState state = this.grid.Binder.GetRecordStateAtRowIndex(rowIndex);
int levelIndex = state.LevelIndex;

Then you can use

GridHierarchyLevel level = this.grid.Binder.GetHierarchyLevel(levelIndex)

to get the GridHierarchyLevel if you know the level index you want.

If I know that I have 3 levels in my grid then can I use

GridHierarchyLevel level = this.grid.Binder.GetHierarchyLevel(0)
GridHierarchyLevel level = this.grid.Binder.GetHierarchyLevel(1)
GridHierarchyLevel level = this.grid.Binder.GetHierarchyLevel(2)

Or
I have to go thru the ‘GetRecordStateAtRowIndex’, my problem is that this way I have to loop thru each row of the grid and then get the levelindex and then actual level.

Please advise.

thanks,

Can i use your suggestion/code in prepareviewstyle event or its too late?

In PrepareViewStyleInfo, I think you can use code like this:

if(e.RowIndex > grid.Model.Rows.HeaderCount)
{
     GridBoundRecordState state = this.grid.Binder.GetRecordStateAtRowIndex(rowIndex);
     int levelIndex = state.LevelIndex;
     if(levelIndex == 0)
         e.Style.BackColor = Color.Red;
     else if(levelIndex == 1)
         e.Style.BackColor = Color.Blue;
     else
         e.Style.BackColor = Color.Green;
}
