How to: Obtain Server Data From the Client

• Dec 17, 2020

This example demonstrates how to obtain server data from the client. A temporary client property - cpPageIndex, is declared within the ASPxGridView.CustomJSProperties event handler. This property holds the index of the page currently active, and can be accessed on the client.

C#

protected void ASPxGridView1_CustomJSProperties(object sender,
   DevExpress.Web.ASPxGridViewClientJSPropertiesEventArgs e) {
    e.Properties["cpPageIndex"] = ASPxGridView1.PageIndex;
}

VB.NET

Protected Sub ASPxGridView1_CustomJSProperties(ByVal sender As Object, ByVal e As DevExpress.Web.ASPxGridViewClientJSPropertiesEventArgs)
    e.Properties("cpPageIndex") = ASPxGridView1.PageIndex
End Sub

ASPX

<input id="Button1" type="button" value="Active Page" onclick="alert(grid.cpPageIndex)" />
