    Limiting Postbacks When Updating Bound Data
    In This Topic

    If your data set is getting lost when you click the Update button, make sure that you have code in your page load event so that you only re-create the bound data when you are loading for the first time and not overwriting it on each post back.

    Using Code

    Use the IsPostBack property.

    Example

    In this example, the if-endif structure surrounding the DataBind method restricts the method from being run on each post back.

    C#
    Copy Code
    if !(Page.IsPostBack)
        {
            ... other code ...
            FpSpread1.DataBind();
         } 
    
    VB
    Copy Code
    If Not Page.IsPostBack Then
            ... other code ...
            FpSpread1.DataBind()
    End If
