GridTreeControl: Freeze a column

[anand rengarajan]

Can I freeze columns (to the left or right), just like how the first column in the tree is frozen in the left by default..

You can freeze columns on the left and right in a GridTreeControl by accessing properties in the gridTreeControl.Model object. Here are some code snippets.

        public MainWindow()
        {
            employees.PopulateWithSampleData(500);

            InitializeComponent();

            this.gridTreeControl1.ModelLoaded += (s, e) =>
            {
                //set up frozen columns on the left
                // value of 1 is rowheader (may be hidden)
                // value of 2 is expand col (default setting)
                //value of 3 will freeze first col to right of expander column
                this.gridTreeControl1.Model.FrozenColumns = 3; 


                //set up frozen columns on the right
                this.gridTreeControl1.Model.FooterColumns = 1; //freezes one column on right
            };
        }

Attached is a sample.
