MultiColumnTreeView resize column

[Administrator]

Hi,


1) How to resize the column, which has tree nodes, to show all the content of all nodes dynamically as the user exapnds the nodes.


2) How do I determine the size of the column to show all the content of all nodes programatically. Is there any method or property on this control?



I am using syncfusion 6.1.0.34.



Thanks,

Hi Rajendra,

Thank you for your interest in Syncfusion Products.

1) Programmatically resizing the Column size when expanding the nodes:

This can be achieved by adjusting the Column width in BeforeExpand event. Kindly refer to the code snippet and the sample provided below:

private void multiColumnTreeView1_BeforeExpand(object sender, Syncfusion.Windows.Forms.Tools.MultiColumnTreeView.TreeViewAdvCancelableNodeEventArgs e)
        {
            int ColWidth = this.multiColumnTreeView1.Columns[0].Width;
            int Node_Width = e.Node.Nodes[0].TextBounds.X + e.Node.Nodes[0].TextBounds.Width;
            if (Node_Width >= ColWidth)
            {             
                    this.multiColumnTreeView1.Columns[0].Width = 25+ e.Node.Nodes[0].TextBounds.X + e.Node.Nodes[0].TextBounds.Width;                            
            }
         }

2) Setting size of the column programmatically:

This can be achieved using MultiColumnTreeView's Columns[index].Width property as described below:

this.multiColumnTreeView1.Columns[0].Width = 100;

Please let me know if any concerns.
