Problem with updating DiagramObject position

[Eamonn John Casey]

Hi,

I got a problem when updating the size and position of DiagramObject using the API.
I have a Boundary object and that code works just fine. But then I try placing (for example an ArchiMate element). The same code will not move the element properly.

Attempt 1:

Code: [Select]

private void UpdateElementOnDiagram(
EAAPI.Diagram diagram, EAAPI.DiagramObject diagramObject,
int left, int right, int top, int bottom)
{
diagramObject.top = top;
diagramObject.left = left;
diagramObject.bottom = bottom;
diagramObject.right = right;
diagramObject.Update();
}
Attempt 2:

Code: [Select]

private void UpdateElementOnDiagram(
EAAPI.Diagram diagram, EAAPI.DiagramObject diagramObject,
int left, int right, int top, int bottom)
{
String styleString = diagramObject.Style.ToString();
String[] styleList = styleString.Split(';');

for (int nIndex = 0; nIndex < styleList.Count(); nIndex++) {
if (true == styleList[nIndex].Contains("l=")) {
styleList[nIndex] = String.Format("l={0}", left);
} else if (true == styleList[nIndex].Contains("r=")) {
styleList[nIndex] = String.Format("r={0}", right);
} else if (true == styleList[nIndex].Contains("t=")) {
styleList[nIndex] = String.Format("t={0}", top);
} else if (true == styleList[nIndex].Contains("b=")) {
styleList[nIndex] = String.Format("b={0}", left);
}
}
styleString = String.Join(";", styleList);
diagramObject.Style = styleString;

diagramObject.Update();
}
I also do the Diagram.Update()

Any ideas?

Thanks,
Eamonn J.

After updating the diagramobject make sure you refresh the diagram.
Saving the diagram might have an adverse effect and undo the changes you just made.

Also remember that the Y axis is negative starting from 0 at the top.

Thanks,

I used Attempt 1 and negated the top and bottom values and now it Works as expected.
