Change postion nodes

[Alberto Munoz]

Hi!

I'm using your diagram with OrgChartLayoutManager.

I want change the position of some nodes. I want the nodes in another row.
I have probed this:
CType(node, IUnitIndependent).SetPinPoint(New PointF(nodo.PinPoint.X, height+80), MeasureUnits.Pixel)

But this does not work with OrgChartLayoutManager. What can I do?

Thanks!!!

Hi Alberto,

If you have to manually set the position of nodes laid out by Layout Manager then you have place that code after the following code, which performs the layout.

this.diagram.LayoutManager.UpdateLayout(null);
CType(node, IUnitIndependent).SetPinPoint(New PointF(nodo.PinPoint.X, height+80), MeasureUnits.Pixel);

Regards,

This is working in most of cases but sometimes "CType(nodo, IUnitIndependent).SetPinPoint(New PointF(nodo.PinPoint.X, nodo.PinPoint.Y + 80), MeasureUnits.Pixel)" does not change the PinPoint.

Where is the problem?

I have just solved it by using this sentence:

Me.DiagramWebControl1.Model.BoundaryConstraintsEnabled = False

Hi Alberto,

Thanks for the update.

Hi!


I am new to syncfusion essential diagram. I am using the Syncfusion winforms diagram library.

My requirement is:

1) I want to draw structure from table(which is having the parent and child nodes).

2) After drawn the structure, if i change the nodes postion(changing the child node from one parent to another parent or adding new symbol(sub node)), these changes should be updated to my table.

Could you please provide some example to achive this requirement

Hi,

Thank you for contacting Syncfusion Products.

1) I want to draw structure from table :

You can draw structure from table by using the following code snippet:

DataTable dt;
 Syncfusion.Windows.Forms.Diagram.Controls.Diagram d1 = dt.Rows[0]["Diagram"] as Syncfusion.Windows.Forms.Diagram.Controls.Diagram;
d1.SaveBinary("d1");
this.diagram2.LoadBinary("d1");

2) If I change the nodes position, these changes should be updated to my table:

You can update the changes to table by using the following code snippet:

 	    DataTable dtNodes;
            dtNodes = new DataTable();
            for (int i = 0; i < diagram1.Model.Nodes.Count; i++)
            {
                dtNodes.Columns.Add(new DataColumn(string.Format("Node{0}", i), typeof(object)));
            }          
          
            foreach (INode objINode0 in diagram1.Model.Nodes)
            {               
                if (objINode0 is Node)
                {
                    DataRow dr = dtNodes.NewRow();
                    for (int j = 0; j < diagram1.Model.Nodes.Count; j++)
                        dr[j] = objINode0; 
                     dtNodes.Rows.Add(dr);
                     dtNodes.AcceptChanges();
                }
            }

Please try this and let me know if this helps.

Thanks,
Melba
