MultiLine text node can be created using OwnerDrawNode property. Subscribe to the event BeforeNodePaint and change the size of the TreeNodeAdv according to the size of the string.Size of the string could be calculated by using MesureString method.Then draw the text using Draw method C# // Creating multiline text nodes private void treeViewAdv1_BeforeNodePaint(object sender, Syncfusion.Windows.Forms.Tools.TreeNodeAdvPaintEventArgs e) { // Paint a custom background around the text area: TreeNodeAdv node = e.Node; Brush foreBrush = new SolidBrush(Color.Red ); System.Drawing.SizeF tSize = e.Graphics.MeasureString( "MultiLine \nText", node.Font ); e.Node.Height = tSize.ToSize().Height; e.Graphics.FillRectangle(new SolidBrush(Color.LightBlue ), e.Node.Bounds.X , e.Node.Bounds.Y , e.Node.Bounds.Width , e.Node.Height ); e.Graphics.DrawString("MultiLine \nText", node.Font, foreBrush, node.TextBounds.Right + 2,node.Bounds.Y + (node.Height-node.TextBounds.Height)/2); } VB ' Creating multiline text nodes Private Sub TreeViewAdv1_BeforeNodePaint(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Tools.TreeNodeAdvPaintEventArgs) Handles TreeViewAdv1.BeforeNodePaint Dim node As TreeNodeAdv Dim foreBrush As Brush Dim tSize As SizeF node = e.Node foreBrush = New SolidBrush(Color.Red) tSize = e.Graphics.MeasureString("MultiLine " & vbCrLf & "Text", node.Font e.Node.Height = tSize.ToSize().Height e.Graphics.FillRectangle(New SolidBrush(Color.LightBlue), node.Bounds) e.Graphics.DrawString("MultiLine " & vbCrLf & "Text", node.Font, foreBrush, node.TextBounds.Right + 2, node.Bounds.Y + (node.Height - node.TextBounds.Height) / 2) End Sub |
