Zoom the Diagram based on the Focus Point

In diagram to resize the model, there are a number of options available. These options are differentiated by the type and constraint (enabling/disabling the “SizeToContent” property) which are listed in below.

Model’s LogicalSize property

Using the Model’s LogicalSize property, we can assign/resize the size of the model type as System.Drawing.SizeF. The following code illustrates how to resize the model.

[C#]

diagram1.Model.LogicalSize = new SizeF(500, 500);

[VB]

diagram1.Model.LogicalSize = new SizeF(500, 500)

Model’s DocumentSize property

This property is also used to assign/resize the size of the model type as Syncfusion.Windows.Forms.Diagram.PageSize. The following code illustrates how to resize the model.

[C#]

diagram1.Model.DocumentSize = new PageSize(500, 500);

[VB]

diagram1.Model.DocumentSize = new PageSize(500, 500)

Model’s MinimumSize Property

This property is used to set the minimum size of the Model under the type of System.Drawing.SizeF. But this property is used only when the Model’s SizeToContent property is enabled. Otherwise, it is not considered by the diagram. The following code illustrates to how to set minimum size value.

[C#]

diagram1.Model.MinimumSize = new SizeF(300, 300);

[VB]

diagram1.Model.MinimumSize = new SizeF(300, 300)
