Hello Hamza,

To get the new page size value you can use the following code in PreRender event of Grid and save the new page size to a HiddenField for example:

protected void RadGrid1_PreRender(object sender, EventArgs e)
   {
       GridPagerItem pagerItem = (GridPagerItem)RadGrid1.MasterTableView.GetItems(GridItemType.Pager)[0];
       RadComboBox combo = (RadComboBox)pagerItem.FindControl("PageSizeComboBox");
       HiddenField1.Value = combo.SelectedValue;
   }

Hello Pavlina,

I have used the code and found the error message Out of bounds array index while i have not used any array indexing in the code. Please advise.

Thanks,

Hello Hamza,

I cannot reproduce the issue. Here is the code that I tried.
aspx:

<telerik:RadGrid ID="RadGrid1" AutoGenerateColumns="false" AllowPaging="true"
PageSize="5" OnNeedDataSource="RadGrid1_NeedDataSource"
runat="server"onprerender="RadGrid1_PreRender">
     <MasterTableView CommandItemDisplay="Top">
         <Columns>
          <telerik:GridBoundColumn DataField="EmployeeID" HeaderText="EmployeeID" UniqueName="EmployeeID"></telerik:GridBoundColumn>
         </Columns>
    </MasterTableView>
</telerik:RadGrid>

C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
   {
       GridPagerItem pagerItem = (GridPagerItem)RadGrid1.MasterTableView.GetItems(GridItemType.Pager)[0];
       RadComboBox combo = (RadComboBox)pagerItem.FindControl("PageSizeComboBox");
       Response.Write(combo.SelectedValue);
   }

Please elaborate your scenario if it doesn't help.

Thanks,
Princy.
