The following example shows how to set the Zoom property of a WorkflowView.

This code example is part of the Workflow Monitor SDK Sample from the MainForm.cs file. For more information, see Workflow Monitor Sample.

private void ToolStripComboBoxZoom_SelectedIndexChanged(object sender, EventArgs e)
{
    if (workflowViewHost.WorkflowView == null) return;
    //Parse the value and set the WorkflowView zoom - set to 100% if invalid
    string newZoom = this.toolStripComboBoxZoom.Text.Trim();
    if (newZoom.EndsWith("%"))
        newZoom = newZoom.Substring(0, newZoom.Length - 1);

    if (newZoom.Length > 0)
    {
        try
        {
            this.workflowViewHost.WorkflowView.Zoom = Convert.ToInt32(newZoom);
        }
        catch
        {
            this.workflowViewHost.WorkflowView.Zoom = 100;
        }
    }
    else
    {
        this.workflowViewHost.WorkflowView.Zoom = 100;
    }
}
Private Sub ToolStripComboBoxZoom_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles toolStripComboBoxZoom.SelectedIndexChanged
    If workflowViewHost.WorkflowView Is Nothing Then
        Return
    End If

    'Parse the value and set the WorkflowView zoom - set to 100% if invalid
    Dim NewZoom As String = Me.toolStripComboBoxZoom.Text.Trim()
    If NewZoom.EndsWith("%") Then
        NewZoom = NewZoom.Substring(0, NewZoom.Length - 1)
    End If

    If NewZoom.Length > 0 Then
        Try
            Me.workflowViewHost.WorkflowView.Zoom = Convert.ToInt32(NewZoom)
        Catch
            Me.workflowViewHost.WorkflowView.Zoom = 100
        End Try
    Else
        Me.workflowViewHost.WorkflowView.Zoom = 100
    End If
End Sub

Remarks

Use the zoom feature to enlarge or reduce the size of the components inside the WorkflowView. The AmbientTheme sets the minimum and maximum zoom levels for the WorkflowView.
