Parent Row highlight on GridTreeControl

[Joshua Cauble]

I have been playing with the level styles of the Grid tree control and have a question on applying the styles.  I did figure out that if I create a empty style for the first one I add that the grid retains it's primary root style.  However what I would like to do is setup the control so that if the node is a parent it is shown in a different background color.  The children work from setting the simple style as the second style.  Is there a way to make a style dependant on the haschildnodes property?

This is what I have defined in codebehind right now for a standard tree grid

 GridStyleInfo levelInfo = new GridStyleInfo();

                    GridStyleInfo level1Info = new GridStyleInfo();

                    levelInfo.Background = new SolidColorBrush(Color.FromRgb(0xB2, 0xCC, 0xFF));

                    

                    this.myGrid.LevelStyles.Add(level1Info);

                    this.myGrid.LevelStyles.Add(levelInfo);

Thanks.

Hi Joshua 

 

Thanks for contacting Syncfusion.

 

We have analyzed your query and we can achieve your requirement by listening the QueryCellInfo event.

Please refer the following code snippet.

 

Code Snippet: [C#]

void Model_QueryCellInfo(object sender, GridQueryCellInfoEventArgs e)

        {

            int rowindex = e.Cell.RowIndex;

           

            GridTreeNode node = this.grid.InternalGrid.GetNodeAtRowIndex(rowindex);

               

            if (node != null)

            {

                if (node.HasChildNodes)

                {  

                        this.grid.InternalGrid.Model.RowStyles[rowindex].Background = new SolidColorBrush(Color.FromArgb(255, 239, 200, 230));                       

                }

             }

          }
