Hi,
Can anyone suggest a way to add comment text(editable) in the diagram..

FYI. We have created a custom control derived from ControlNode and and added a TextBlock to that..The TextBlock has MaxWidth and TextWrapping set to 100.And the X,Y position of the comment text is stored in database.Now the problem is the textbox is displayed with the default size of 50,50 automatically and there is noway i could find to display the complete text.
Appreciate your help..

Thanks,

Hi Stoyan,

Thanks for the quick reply..I tried with ShapeNode and called ResizeToFitText() method after assigning the text. Please have a look at my code.

public ShapeNode1(Diagram diagram,Comment comment) : base(diagram)
{
this.Text = comment.TextComment;
this.TextWrapping = System.Windows.TextWrapping.Wrap;
this.MaxWidth = 100;
ResizeToFitText();
Rect rec = this.GetBounds();
rec.X = comment.XPosition;
rec.Y = comment.YPosition;
this.SetBounds(rec, true);
this.UpdateVisuals();
}

But for some reason,the shapenode is displayed without wrapping with respect to the MaxWidth set to 100..Please tell me whats wrong in this code and it would be helpful if u can share some sample code..

Thanks,

Hi Stoyan,
I tried the other approach using TextBlock and unfortunately it did not help me to solve the issue..copied the code for your reference...
public ShapeNode1(Diagram diagram,Comment comment) : base(diagram)
{
var textBlock = new TextBlock
{
Text =comment.TextComment,
TextWrapping = TextWrapping.Wrap,
MaxWidth = 100,
Width = double.NaN,
Height = double.NaN,
FontFamily = FontFamily,
FontSize = FontSize
};
textBlock.UpdateLayout();
Size desiredSize = new Size(
textBlock.ActualWidth + TextMargin.Left + TextMargin.Right + StrokeThickness * 2,
textBlock.ActualHeight + TextMargin.Top + TextMargin.Bottom + StrokeThickness * 2);

Rect newBounds = new Rect(new Point(comment.XPosition, comment.YPosition), desiredSize);
this.SetBounds(newBounds, true);
}
