Parameters

layoutReader
XmlReader

An XmlReader that is created for the serialized layout.

layoutLoadErrors
IList

Examples

This example shows how to load the layout for a specific workflow definition using the LoadDesignerLayout method. An XmlReader object is created using the file name of a designer layout file that was created using SaveDesignerLayout. When the layout has finished loading, any errors that might have occurred are displayed to the user.

public void LoadLayout()
{
    using (XmlReader reader = XmlReader.Create("wfInstanceId.designer.xml"))
    {
        IList layoutLoadErrors = new ArrayList() as IList;
        this.LoadDesignerLayout(reader, out layoutLoadErrors);

        if (layoutLoadErrors.Count > 0)
        {
            System.Text.StringBuilder sb = new System.Text.StringBuilder("Errors:\r\n");
            foreach (WorkflowMarkupSerializationException error in layoutLoadErrors)
            {
                sb.Append(error.Message + "\r\n");
            }
            MessageBox.Show(sb.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
    }
}
Public Sub LoadLayout()
    Using reader As XmlReader = XmlReader.Create("wfInstanceId.designer.xml")

        Dim layoutLoadErrors As IList = CType(New ArrayList(), IList)
        Me.LoadDesignerLayout(reader, layoutLoadErrors)

        If layoutLoadErrors.Count > 0 Then
            Dim sb As New System.Text.StringBuilder("Errors:\r\n")
            For Each errorMessage As WorkflowMarkupSerializationException In layoutLoadErrors
                sb.Append(errorMessage.Message + "\r\n")
            Next
            MessageBox.Show(sb.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)

        End If
    End Using
End Sub
