Windows 7 x64, VS 2008, ASP.Net AJAX v 2010.2.826.35.

I'm auto generating RadGrids from the database using codesmith/nettiers and it works perfectly for some tables but doesn't for others. This particular issue only seems to be IE as it works in other browsers. It also happens whether there is data or not.

Bascially it gets confused with the position on the scrollbar and as you scroll right it can reset back to the left or as you reach the end of the table it loses track of earlier columns and just shows the last page with the scrollbar on the left and then last field with the scrollbar disabled.

If I drag the scrollbar to the right it continuosly moves left/right and occasionalyy I get an 'Unspecified Error' on:-

setTimeout(

"Telerik.Web.UI.Grid.frozenScrollHanlder("+this._frozenScrollCounter+")",0);

I think the issue is a problem with the column headers - below is a single column for a RadGrid that scrolls perfectly.

<telerik:GridBoundColumn DataField="LabourCardNumber" HeaderText="Labour Card Number" SortExpression="[LabourCardNumber]" HeaderStyle-Width="100px" HeaderStyle-VerticalAlign="Top" ItemStyle-VerticalAlign="Top" />

if I do something as simple as changing the HeaderText to "Labour Card Number Reference" the horizontal scrollbar no longer functions correctly in IE (6,7 or 8).

Think its something to do with the length of the HeaderText. Can you confirm its an issue and being looked into?

Thanks

There are several inconsistencies in the horizontal scrollbar and IE so I thought I'd reproduce the error using your VB scrolling code from the RadControls for ASP.NET AJAX Q2 2010 Live demos.

I thought I'd have to make changes to the code to show the scolling issues, however, the unchanged code immediately shows a similar but different problem.

I attach 3 images, the first the initial image showing the northwind data, the second showing the data with the scrollbar to the right both with no problem. Now I simply click on the left of the scollbar to go back to the left and rather than reverting back to RadGrid1 as it should I get the RadGrid3 image.

The horizontal scrollbar has now completely gone and I am simply leff with the ProductId and Units on Order columns.

Do I need to issue a support ticket or is someone looking into this?

The standard code generates EntityGridViews and its relatively simple to change the grid definition and data columns to use RadGrid .

I've actually changed it so that the GUI is all VB rather than C# but here's my Entity.aspx.cst file which you should be able to convert easily enough.
