Create Palette with GroupNode where GroupNode contain multiple ControlNodes.
Create Palette with GroupNode where GroupNode contains multiple ControlNodes.
In the diagram control, we can add a group object that contains multiple ControlNodes into the symbol palette.
The following code illustrates adding the group with multiple ControlNodes to the palette.
[C#]
// Initializing the label control
System.Windows.Forms.Label label = new System.Windows.Forms.Label();
label.Size = new System.Drawing.Size(200, 25);
label.Text = "Label";
label.Name = "Label";
label.TextAlign = ContentAlignment.MiddleCenter;
// Initializing the textbox control
TextBox textbox = new TextBox();
textbox.MinimumSize = new System.Drawing.Size(200, 400);
textbox.Text = "TextBox";
textbox.Name = "TextBox";
// Adding a textbox to the diagram's control node
ControlNode textboxCtrlNode = new ControlNode(textbox, new RectangleF(0, 0, 200, 100));
textboxCtrlNode.Name = "TextBoxControl";
textboxCtrlNode.ActivateStyle = ActivateStyle.ClickPassThrough;
// Adding a label to the diagram's control node
ControlNode labelCtrlNode = new ControlNode(label, new RectangleF(0, 100, 200, 25));
labelCtrlNode.ActivateStyle = ActivateStyle.ClickPassThrough;
labelCtrlNode.Name = "LabelControl";
Group group = new Group();
group.Name = "GroupNode";
// Adding symbols to the group node
group.AppendChild(textboxCtrlNode);
group.AppendChild(labelCtrlNode);
diagram1.Model.AppendChild(group);
// Adding symbols to the palette
SymbolPalette symbol = new SymbolPalette();
symbol.AppendChild(group);
paletteGroupBar1.AddPalette(symbol);
[VB]
' Initializing the label control
Dim label As New System.Windows.Forms.Label()
label.Size = New System.Drawing.Size(200, 25)
label.Text = "Label"
label.Name = "Label"
label.TextAlign = ContentAlignment.MiddleCenter
' Initializing the textbox control
Dim textbox As New TextBox()

textboxCtrlNode.ActivateStyle = ActivateStyle.ClickPassThrough
' Adding a label to the diagram's control node
Dim labelCtrlNode As New ControlNode(label, New RectangleF(0, 100, 200, 25))
labelCtrlNode.ActivateStyle = ActivateStyle.ClickPassThrough

Dim group As New Group()
group.Name = "GroupNode"
