I've created a datatable using the following query:
select str(-abs(100),10,2) as crash
(a negative number cast to string)

When I use this datatable in a grid and export it to excel, I'll get the folowwing error:
We found a problem with this formula. Try clicking Insert Function on the Formulas tab to fix it.\n\nNot trying to type a formula? When the first character is an equal (=) or minus (-) sign, RadSpreadsheet thinks it is a formula. For example, when you type =1+1 the cell shows 2.

I've implemented the workarround in https://www.telerik.com/forums/output-to-excel-error
(The cell has the Format attribute set to "@")
This works for regular strings starting with a dash, but not working for the specific situation described before.

Using SVG in Binary Image for RadLoadingPanel

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" BackgroundPosition="Center"

EnableSkinTransparency="True" BackColor="Transparent" BackgroundTransparency="100" >

<div style="vertical-align:middle; text-align:center">

<telerik:RadBinaryImage ID="RadBinaryImage1" ResizeMode="None" ImageUrl="../../Images/CustomLoader2.svg" runat="server" />

</div>

</telerik:RadAjaxLoadingPanel>

It works to show the SVG image while a chart/grid is loading, however, the background isn't transparent and the SVG image isn't centered, x/y axis with the object it's loading over top of.

Can you amazing Telerik Gurus please help! Thanks so much! Hope you have a great weekend!

SharePoint 2010 - Telerik CAPTCHA - Hangs up randomly during Next Image.

Hello,

We have a SharePoint 2010 environment. We put the Telerik CAPTCHA to a web part but are experiencing issues with WFE server(s) hanging at random times when the “Next Image” was used. It would always come up the first time and could be successfully used but then randomly it would not work when ‘new image’ was requested from the link and it will just hang.

We would get the following error: Uncaught Sys.WebForms.PageRequestManagerTimeoutException: The server request timed out.

It works when there is only one WFE is involved. We have multiple WFEs and it would fail randomly.

Any idea/thoughts about the issue?

Thanks,

Ricky

Client UI & asmx

Hi, there is a way to customize the media player so that:
1. Do not show the posters, I have no pictures to show and I do not want to show a <img src = "">
2. The playlist is default opened, if i set width to 100% when i try to open the playlist item i'm not able to see it on the page. I want to fix width for player and for playlist box;
3. Do not show the playlist opening / closing buttons;
4. Can i add some additionals info to "MediaPlayerVideoFile" or "MediaPlayerAudioFile" and then (on user first play of a file) call a client-side code that increments statistics for play via asmx ?

Header Context Menu - Show/Hide Column checkboxes initially shown as unhecked (hidden)

Using Using RadControls 2008.3.1314, Internet Explorer 6, ASP.NET 2.0.50727.

I am experiencing an oddity with the Grid Header Context Menu in both my application and on the live demo page. The Grid loads and all columns are visible, but when I right click to access the header context menu, all the columns in the "Columns" context sub-menu have an unchecked state, as if there were not visible. However, as soon as I access the header context menu a second time, the checked states correctly match the actual visibility of the Grid's columns. Then, if I force the Grid to rerender (sort, group, ungroup, etc.), the context menu shows all unchecked again even though the columns are actually visible.

Setting Display="true" for any given GridBoundColumn has no effect on this behavior. Does anyone else experience this behavior on the demo page?

Here's how I'm defining my RadGrid:

    
            <telerik:RadGrid ID="RadGrid2" runat="server" DataSourceID="sdsFreTats" GridLines="None" 
        
                ShowGroupPanel="True" Skin="Office2007" AllowSorting="True" AutoGenerateColumns="False" 
        
                AllowPaging="True" PageSize="40" ShowFooter="True">  
        
                <ClientSettings AllowDragToGroup="True" AllowColumnsReorder="True" ReorderColumnsOnClient="True" 
        
                    AllowColumnHide="true">  
        
                    <Resizing AllowColumnResize="true" /> 
        
                    <Selecting AllowRowSelect="True" /> 
        
                    <Scrolling AllowScroll="True" UseStaticHeaders="True" /> 
        
                </ClientSettings> 
        
                <MasterTableView DataSourceID="sdsFreTats" GroupLoadMode="Client" TableLayout="Fixed" EnableHeaderContextMenu="true">  
        
                    <Columns> 
        
                     ...  
        
                    </Columns> 
        
                    <PagerStyle Mode="NextPrevAndNumeric" /> 
        
                </MasterTableView> 
        
                <HeaderContextMenu Skin="Office2007">  
        
                    <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                </HeaderContextMenu> 
        
                <FilterMenu Skin="Office2007">  
        
                    <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                </FilterMenu> 
        
                <PagerStyle Mode="NextPrevAndNumeric" /> 
        
            </telerik:RadGrid>
