Question

I have a RadGrid in my ASP.Net app and I have set the AllowPaging to True and PageSize to 10, now it load 10 items per RadGridPage which is what I wanted, but as soon as I press Next Page button (Arrow look button) nothing loads and RadGrid gets empty.
How can I make it work normal?

protected void Page_Load(object sender, EventArgs e)
    {
        PopulateGridOnLoad();
    }
private void PopulateGridOnLoad()
    {
        rgCustomers.DataSource = odsCustomers;
        // your datasource type
        rgCustomers.MasterTableView.VirtualItemCount = 28;
        //your datasource type total/count
        rgCustomers.CurrentPageIndex = rgCustomers.MasterTableView.CurrentPageIndex;
        rgCustomers.Rebind();

    }

protected void grdName_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
    {

        rgCustomers.DataSource = odsCustomers;
        // your datasource type
        rgCustomers.MasterTableView.VirtualItemCount = 28;
        //your datasource type total/count
        rgCustomers.CurrentPageIndex = rgCustomers.MasterTableView.CurrentPageIndex;
        //Donot rebind here
    }

    protected void btnLoad_Click(object sender, EventArgs e)
    {
        odsCustomers.SelectParameters["CustomerFullName"].DefaultValue = txtFullName.Text;
        odsCustomers.SelectParameters["CustomerMelliCode"].DefaultValue = txtMelliCode.Text;
        odsCustomers.SelectParameters["CustomerHomeAddress"].DefaultValue = txtHomeAddressPart.Text;
        odsCustomers.SelectParameters["CustomerWorkAddress"].DefaultValue = txtWorkAddressPart.Text;
        rgCustomers.DataSource = odsCustomers;
        rgCustomers.DataBind();

    }

After a long time I found the solution, the problem involved 2 minor issues :
1.I had both DataSource (in code) and DataSourceID (property) set and they didn’t work together well
2.I had both AllowPaging and AllowCustomPaging set to true, when they are both true neither works 🙂 that’s the telerik team you know, but they are great I was kidding
