GridGroupingControl - navigating child records with the arrow keys

[Dave Busch]

Hello - I have a parent table where some of the records have child rows in an associated child table. This is similar to the 'RecordCollapseEvents_CS' example project that is on another post.

The up/down arrow keys work fine if all of the parent records are collapsed - either key navigates through the records up or down. The problem is when I expand one or more of the parent rows to show their child rows. This produces some strange behavior - namely that the "child" rows are skipped over when pushing the up/down arrow keys. I cannot seem to navigate to the child rows at all using the up/down arrow keys.

I would be happy to provide a simple example if you need it, please let me know. Thanks for your time.

Hi Dave,

I am not able to reproduce this problem here in any of our samples. Navigating to the childrecords from the parent records through the arrow keys works fine without any issues. I have attached a small video file and a sample showing this. Please check them out from the below download link.

Are you seeing this issue in the above mentioned sample? Please let us know.

Thanks for the quick response! The problem is that I changed the grid to only select one row, and highlight that row (not individual cell selection.) I changed two things:

1) this.gridGroupingControl1.TableOptions.ListBoxSelectionMode = System.Windows.Forms.SelectionMode.One;

2) Added an event - 'TableControlCurrentCellActivating'

private void gridGroupingControl1_TableControlCurrentCellActivating(object sender, GridTableControlCurrentCellActivatingEventArgs e)
{
//Whole row selection
e.Inner.ColIndex = 0;
}

This is causing the same behavior I am seeing in my grid - please see that attached sample.

Thanks again!

Hi Dave,

The code in the TableControlCurrentCellActivating was causing the problem. Instead, you can use the below property settings to achieve the whole row selection.

this.gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.One;
this.gridGroupingControl1.TableOptions.ListBoxSelectionCurrentCellOptions = GridListBoxSelectionCurrentCellOptions.HideCurrentCell;

Thanks for using Syncfusion Products.
Have a nice time.

Hi Rajagopal,

This solution does not work at all - the "HideCurrentCell" value does NOT even exist! There are three choices for the 'GridListBoxSelectionCurrentCellOptions' enumeration:

-MoveCurrentCellWithMouse
-None
-WhiteCurrentCell

Is this the correct enumeration, and which value is the one I need to use? I selected the "WhiterCurrentCell" and it does not work - the "whole row selection" does not work.

Can you please see my example (attached above), and tell me what I need to change to get this to work? Or, if you could just make the changes in that project and send it back to me, that would be very helpful. Thanks for your time!

Actually Rajagopal, this seems to allow me to select the entire row, and use the arrow keys to navigate, but I am now allowed to "click inside" of the cells within the row - which is a problem. The original code I had within the "TableControlCurrentCellActivating" event was prohibiting users from doing this. How can I add this to your solution?
