Load(Stream) Method

Loads a layout from a stream, including all properties.
Syntax
'Declaration
 
Public Overloads Sub Load( _
   ByVal stream As Stream _
) 
public void Load( 
   Stream stream
)

Parameters

stream
The stream to read.
Remarks

Invoking this method loads a layout, created by invoking the Save(Stream) method, from a stream. The stream can be used to retrieve the Layout data from different sources, such as a file on disk, an Internet location or from memory.

The Clone and CopyFrom methods can be invoked to make a duplicate of a layout.

Example
Following code shows you how to save and load the saved layout. You can save the layout of an UltraGrid to a stream and later load it to the same UltraGrid or a different UltraGrid. Following code sample contains two button handlers. One has the code to save the layout to a file and the other one has the code to load the layout from a file.

Imports Infragistics.Shared
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinGrid

  Private LAYOUT_FILE_PATH As String = "c:\\test.layout"

  Private Sub Button90_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button90.Click

      ' Following code saves the ultraGrid1's layout to a file.
      Dim fs As System.IO.FileStream = Nothing

      Try
          ' Open a new file to save the layout to.
          fs = New System.IO.FileStream(LAYOUT_FILE_PATH, System.IO.FileMode.Create, System.IO.FileAccess.Write, System.IO.FileShare.None)
      Catch exc As Exception
          MessageBox.Show(Me, "Unable to create a new file " & LAYOUT_FILE_PATH & " for saving the layout. " & exc.Message, "Unable to create file", MessageBoxButtons.OK, MessageBoxIcon.Error)
          Return
      End Try

      ' Save the layout to the file.
      Me.UltraGrid1.DisplayLayout.Save(fs, PropertyCategories.All)

      ' Close the file.
      fs.Close()

  End Sub

  Private Sub Button91_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button91.Click

      ' Following code loads the saved layout from a file.
      Dim fs As System.IO.FileStream = Nothing

      Try
          ' Open the file where the layout has been saved before.
          fs = New System.IO.FileStream(LAYOUT_FILE_PATH, System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.Read)
      Catch exc As Exception
          MessageBox.Show(Me, LAYOUT_FILE_PATH & " file not found. " & exc.Message, "Unable to open file", MessageBoxButtons.OK, MessageBoxIcon.Error)
          Return
      End Try

      ' Load the layout from the input stream by calling Load method. It is very important that you reset the
      ' Position of the file stream to where the layout data begins in case the file stream has
      ' been read from previously.
      fs.Position = 0
      Me.UltraGrid1.DisplayLayout.Load(fs, PropertyCategories.All)

      ' Close the file
      fs.Close()

  End Sub
