WinForms VirtualGrid Overview

Save/Load layout functionality gives your applications the opportunity to preserve user grid settings such as column order and restore them later. Those layout settings are written in a XML file.

Here is a sample demonstrating how you can implement a Save Layout button event handler:

The Save and Load Layout is part of Telerik UI for WinForms, a professional grade UI library with 160+ components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial.

Save layout

private void SaveButton_Click(object sender, EventArgs e)
{
    string s = "default.xml";
    SaveFileDialog dialog = new SaveFileDialog();
    dialog.Filter = "xml files (*.xml)|*.xml|All files (*.*)|*.*";
    dialog.Title = "Select a xml file";
    if (dialog.ShowDialog() == DialogResult.OK)
    {
        s = dialog.FileName;
    }
    this.radVirtualGrid1.SaveLayout(s);
}

Private Sub SaveButton_Click(sender As Object, e As EventArgs) Handles RadButton1.Click
    Dim s As String = "default.xml"
    Dim dialog As New SaveFileDialog()
    dialog.Filter = "xml files (*.xml)|*.xml|All files (*.*)|*.*"
    dialog.Title = "Select a xml file"
    If dialog.ShowDialog() = DialogResult.OK Then
        s = dialog.FileName
    End If
    Me.RadVirtualGrid1.SaveLayout(s)
End Sub

The code snippets below demonstrates how you can implement a Load Layout button event handler: 

Load layout

private void LoadButton_Click(object sender, EventArgs e)
{
    string s = "default.xml";
    OpenFileDialog dialog = new OpenFileDialog();
    dialog.Filter = "xml files (*.xml)|*.xml|All files (*.*)|*.*";
    dialog.Title = "Select a xml file";
    if (dialog.ShowDialog() == DialogResult.OK)
    {
        s = dialog.FileName;
    }
    this.radVirtualGrid1.LoadLayout(s);
}

Private Sub LoadButton_Click(sender As Object, e As EventArgs) Handles RadButton2.Click
    Dim s As String = "default.xml"
    Dim dialog As New OpenFileDialog()
    dialog.Filter = "xml files (*.xml)|*.xml|All files (*.*)|*.*"
    dialog.Title = "Select a xml file"
    If dialog.ShowDialog() = DialogResult.OK Then
        s = dialog.FileName
    End If
    Me.RadVirtualGrid1.LoadLayout(s)
End Sub

Once the layout is being loaded the LayoutLoaded event is being thrown in order to notify that the load process is being finished.
