Grid header and footer display error on IE8

I have used the radgrid to show some data to my customer, when I enable the 'AllowScroll' and 'UseStaticHeaders' function, there is a display problem in IE8 as attached image. The last part of the header and footer disappear.

I have tested for firefox 3.5.2, all things work fine. My Telerik.Web.UI.dll file version is 2010.2.929.35.

Here is some code for my grid

.ascx part:

<asp:Panel id="TelerikSummaryReportsPanel" runat="server" style="margin-top:10px;">
    <telerik:RadGrid ID="gridReports_Telerik" runat="server"
                EnableAjaxSkinRendering="true"
                GridLines="Horizontal" CellPadding="0" BorderStyle="None"
                ClientSettings-AllowColumnHide="true" ClientSettings-EnableRowHoverStyle="true"
                ShowStatusBar="true" ShowHeader="true" AllowSorting="true"
                ShowFooter="true" RegisterWithScriptManager="true"
                EnableViewState="true"
                AllowFilteringByColumn="true"
                AllowMultiRowSelection="true">
        <GroupingSettings CaseSensitive="false" />
        <ClientSettings>
            <Scrolling EnableVirtualScrollPaging="false" />
            <Scrolling AllowScroll="true" UseStaticHeaders="true" />
            <Selecting AllowRowSelect="true" EnableDragToSelectRows="true" />
            <Resizing AllowColumnResize="true" EnableRealTimeResize="true" ShowRowIndicatorColumn="true"
                      ResizeGridOnColumnResize="true" AllowRowResize="false" ClipCellContentOnResize="false" />

        </ClientSettings>

    </telerik:RadGrid>

</asp:Panel>

And I control the height in the C# code, if no height setting or it is larger than the actual height of data, no problem occurs.

.ascx.cs file:

    protected void gridReports_DataBound(object sender, EventArgs e)
    {
        RadGrid Grid = (RadGrid)sender;

        int rowCount = Grid.Items.Count;
        if (rowCount > 25)
        {
            gridReports_Telerik.Height = 700;
        }
    }

What can I do or test to solve this problem? Thanks a lot if you can give some advice

Hi,

How would we disable viewstate for all controls in an application?

Is there a list of which radcontrols uses viewstate and what they store in it?

Thanks.

Combos in tabs as text

Hello,

I have a requirement that needs comboboxes in the tabs(instead of Text) and I need to display the data as per the selection on that particular tab, I don't know if it is feasible, I was planning on using Ajax controls for this page, I am just wondring if the tab strip supports it, if not what are the alternatives.

I am adding a screenshot that would give you a rough idea on the requirements. Your input is greatly appriciated.

Thanks,
SC

RadGrid Filter Templates With EntityDataSource

I'm having trouble implementing a solution similar to the example from the second grid on the following page to do a "between" filter on a date column in a RadGrid.

http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filtertemplate/defaultcs.aspx

As far as I can tell I have implemented all the relevant stuff from the example and the only difference is I'm using an EntityDataSource instead of a SqlDataSource. However, when I select a date from either box I get the following error.

The datetime literal value '2010-06-02' is not valid. Near line 6, column 17.

I used the small example below to reproduce the error.

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

Text "Select" Temporarily displayed in Filter

Hi All,

I am using RadControls for ASP.NET Q3 2010. I have a radgrid which has filtering enabled. When toggling the filter button on for the first time, the text "select" is temporarily displayed where the filter control should be. The text is displayed for a moment then the filter controls are rendered correctly. See attachment. I am not sure what would cause this behavior.

How do I prevent "select" from being displayed at all when the filter controls are being rendered?

Regards,
Cliff

RadDockZone - Couldn't get the position

Hi,
I have used RadDockZone to perform drag and drop. The Drag and Drop works fine. But the problem is i couldn't save or maintain the order in which the final drag and drop leaves.
i.e if initially, the order is as

Item A - dock[0]
Item B - dock[1]
Item C - dock[2]
Item D - dock[3]
After several drag and drop, the order is changed as
Item C - dock[2]
Item D - dock[3]
Item B - dock[1]
Item A - dock[0]

I couldn't save the position that 'Item C' is now in 1st position, 'Item D' in 2nd position...etc of the order.
Is there any way to save the actual position i.e the order ?
