Draw a structure from table

[Ven]

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 Support.

1) I want to draw structure from table :

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

[CS]
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:

[CS]
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 refer to the sample in the following link which illustrates this:
