Radgrid Pagination Disappears and Appears

[Gayathri]

Hi,

I am using telerik RadGrid in my web page to list data and i am using pagination .
<PagerStyle Mode="NextPrevAndNumeric" VerticalAlign="Bottom" Position="Bottom" AlwaysVisible="true" />
Dll -  Telerik.Web.UI
Version - 2011.1.519.40
When changing the page size from 10 to 20/50 the pagination control disappears and then appears.
I have attached the screen shots for the issue.
I want the pagination to be static and it must not disappear
Please let me know how to fix the issue.

Thanks
Gayathri

Hi Gayathri,

Such an issue is not supposed to be occurring.Can u please try below simple code and check if the issue is existing.If you are not able to resolve,please provide your full code both aspx and C#.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false"
    GridLines="None" AllowPaging="true" >
    <MasterTableView>
        <PagerStyle Mode="NextPrevAndNumeric" VerticalAlign="Bottom" Position="Bottom" AlwaysVisible="true" />
        <Columns>
            <telerik:GridBoundColumn UniqueName="OrderID" DataField="OrderID" HeaderText="OrderID" />
            <telerik:GridBoundColumn DataField="ShipCity" HeaderText="ShipCity" UniqueName="ShipCity" />
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

Thanks,

Hi Gayathri,

This issue has already been addressed. Please download and upgrade your application to the latest RadControls version and the problem should be resolved when PagerStyle-AlwaysVisible is enabled.

Looking forward to your reply.
