NodeProgressBar node control

NodeProgressBar node control lets you display a progress bar inside a treeview node.

To start using this node control, specify its size. To do that, use the node control`s Size property. By default, its value is 50x16 pixels.

Data binding

A progress bar has three parameters: progress value, minimum value, and maximum value.

To bind these parameters to node class members, adjust the appropriate member names of the node via the ValueDataFieldName, ValueDataFieldName, and MaxValueDataFieldName node control properties, respectively.
ValueDataFieldName has a default value, ‘ProgressValue’, while MinValueDataFieldName and MaxValueDataFieldName have none.
If MinValueDataFieldName or MaxValueDataFieldName values aren`t set explicitly, the progress bar`s minimum value is 0, and the maximum value is 100.

Example:

// Custom node class with members for the progress bar node control.
class ProgressNode : Node
{
  public int Progress;
  public int MinValue;
  public int MaxValue;
 
  public ProgressNode(string pText) : base(pText)
  {
  }
}
 
// NodeProgressBar node control usage example.
NodeTextBox tb = new NodeTextBox();
tb.AttachTo(tree);
 
NodeProgressBar pb = new NodeProgressBar();
pb.ValueDataFieldName = "Progress";
pb.MinValueDataFieldName = "MinValue";
pb.MaxValueDataFieldName = "MaxValue";
pb.AttachTo(tree);
 
ProgressNode n = new ProgressNode("Operation progress:");
n.Progress = 80;
n.MinValue = 0;
n.MaxValue = 200;
n.AttachTo(tree);
