Example 1
This example shows how to save or restore the ASPxGridView layout to or from a data store.
protected void ASPxGridView1_ClientLayout(object sender,
DevExpress.Web.ASPxClientLayoutArgs e) {
if (e.LayoutMode == DevExpress.Web.ClientLayoutMode.Saving) {
SaveUserLayoutToDatabase(userID, "AccountGrid", e.LayoutData);
}
else {
if (System.IO.File.Exists(fileName))
e.LayoutData = RestoreUserLayoutFromDatabase(userID, "AccountGrid");
}
}
Protected Sub ASPxGridView1_ClientLayout(sender As Object,_
e As DevExpress.Web.ASPxClientLayoutArgs)
If e.LayoutMode = DevExpress.Web.ClientLayoutMode.Saving Then
SaveUserLayoutToDatabase(userID, "AccountGrid", e.LayoutData)
Else
If File.Exists(fileName) Then
e.LayoutData = RestoreUserLayoutFromDatabase(userID, "AccountGrid")
End If
End If
End Sub
Example 2
This example shows how to save and restore the previously saved layout manually. The grid calls the ASPxClientGridView.PerformCallback method to send a callback to the server when a user clicks the Save Layout or Load Layout button. This generates the server-side ASPxGridView.CustomCallback event. Handle this event to save or restore the grid's layout.
protected void ASPxGridView1_CustomCallback(object sender,
DevExpress.Web.ASPxGridViewCustomCallbackEventArgs e) {
if (e.Parameters == "save") {
SaveUserLayoutToDatabase("userID", "GridLayout", ASPxGridView1.SaveClientLayout());
}
if (e.Parameters == "load") {
ASPxGridView1.LoadClientLayout(GetUserLayoutFromDatabase("userID", "GridLayout"));
}
}
Protected Sub ASPxGridView1_CustomCallback(ByVal sender As Object, ByVal e As DevExpress.Web.ASPxGridViewCustomCallbackEventArgs)
If e.Parameters = "save" Then
SaveUserLayoutToDatabase("userID", "GridLayout", ASPxGridView1.SaveClientLayout())
End If
If e.Parameters = "load" Then
ASPxGridView1.LoadClientLayout(GetUserLayoutFromDatabase("userID", "GridLayout"))
End If
End Sub
