Hi!

I create nodes programmatically in my constructor. The horizontal scrollbar is not displayed and I can't pan. It's like the size of the graphic is not correct. If I resize the window and move the last node, it works fine afterwards... Do you know what is wrong with my code?

Here is the code in the constructor:

int nodeCount = 20;
int xShift = 200;
int yShift = 100;
int xMax = 1000;
float width = 100;
int height = 75;
float xPos = 0;
float yPos = 0;
for (int i = 0; i < nodeCount; i++)
{
    TableNode node = new TableNode(this.diagram1);
    this.diagram1.Items.Add(node);

    int number = i + 1;
    node.Caption = "Node " + number;
    node.Bounds = new RectangleF(xPos, yPos, width, height);

    xPos += xShift;

    if (xPos >= xMax)
    {
        xPos = 0;
        yPos += yShift;
    }
}

    //

All this code comes from a little sample program I did to narrow down the problem... There isn't any more code except for auto-generated one. It's just a window with a diagram view in it.

Thanks!

Note: the same problem occurs after loading a saved graph.

Thanks Stoyan!

It works great. I added it after loading a saved graph as well and it solves both problems.
