Accessing the Elements of Advanced Type Pager

When using the advanced grid pager/slider, you can customize the properties of the buttons or labels inside the pager or the slider pager itself. The following steps describe how to access these controls:

1. Create a handler for the grid's ItemCreated event.

2. In the event handler, check if e.Item is an instance of GridPagerItem.

3. Use the FindControl method of e.Item to locate the controls inside the pager. The following table lists the ID's of the controls in the pager when Mode is "NextPrevAndNumeric":

   Control	Type	ID
   "Page Size:" text	Label	ChangePageSizeLabel
   "Page Size" combo box	RadComboBox	PageSizeComboBox

   Example:

   C#

   protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
   {
       if (e.Item is GridPagerItem)
       {
           Label lblPageSize = (Label)e.Item.FindControl("ChangePageSizeLabel");
           lblPageSize.Text = "Number of items:";
       }
   }
   

   VB

   Protected Sub RadGrid1_ItemDataBound(sender As Object, e As GridItemEventArgs) Handles RadGrid1.ItemDataBound()
       If TypeOf e.Item Is GridPagerItem Then
           Dim lblPageSize As Label = DirectCast(e.Item.FindControl("ChangePageSizeLabel"), Label)
           lblPageSize.Text = "Number of items:"
       End If
   End Sub
   

4. The following table lists the ID's of the controls in the pager when Mode is "Advanced" or "Slider":

 

Control	Type	ID
"Go to page" text	Label	GoToPageLabel
"Go to page" input	RadNumericTextBox	GoToPageTextBox
"Go to page" " of " text	Label	PageOfLabel
"Go to page" link button	Button	GoToPageLinkButton
"Change page size" text	Label	ChangePageSizeLabel
"Change page size" input	RadNumericTextBox	ChangePageSizeTextBox
"Change page size" link button	Button	ChangePageSizeLinkButton
Slider pager	RadSlider	GridSliderPager

<telerik:RadGrid
    ID="RadGrid1"
    runat="server"
    Width="95%"
    Skin="Vista"
    AllowSorting="True"
    DataSourceID="SqlDataSource1"
    AllowPaging="True" PageSize="5"
    OnItemCreated="RadGrid1_ItemCreated">
    <PagerStyle Mode="Advanced" />
    <MasterTableView Width="100%" DataSourceID="AccessDataSource1" />
</telerik:RadGrid>      

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridPagerItem)
    {
        RadNumericTextBox goToPageText = (RadNumericTextBox)e.Item.FindControl("GoToPageTextBox");
        goToPageText.Width = Unit.Pixel(80);
        goToPageText.ShowSpinButtons = true;
        goToPageText.Style.Add("color", "gray");
        Label changePageLabel = (Label)e.Item.FindControl("GoToPageLabel");
        changePageLabel.Visible = false;
    }
}

Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As GridItemEventArgs) Handles RadGrid1.ItemCreated
    If TypeOf e.Item Is GridPagerItem Then
        Dim goToPageText As RadNumericTextBox = CType(e.Item.FindControl("GoToPageTextBox"), RadNumericTextBox)
        goToPageText.Width = Unit.Pixel(80)
        goToPageText.ShowSpinButtons = True
        goToPageText.Style.Add("color", "gray")
        Dim changePageLabel As Label = CType(e.Item.FindControl("GoToPageLabel"), Label)
        changePageLabel.Visible = False
    End If
End Sub

When setting the PageOfLabel, in order to to display the page count number, you would need to append it to the label text as demonstrated below:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridPagerItem)
    {
        GridPagerItem item = e.Item as GridPagerItem;
        Label pageOfLabel = e.Item.FindControl("PageOfLabel") as Label;
        pageOfLabel.Text = "OF " + item.Paging.PageCount.ToString();
    }
}

Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs)
    If TypeOf e.Item Is GridPagerItem Then
        Dim item As GridPagerItem = TryCast(e.Item, GridPagerItem)
        Dim pageOfLabel As Label = TryCast(e.Item.FindControl("PageOfLabel"), Label)
        pageOfLabel.Text = "OF " + item.Paging.PageCount.ToString
    End If
End Sub
