Passing parameters from Javascript to custom AsyncHandler

Hello,

Is there a way to include parameters from Javascript to be sent to a custom AsyncUploadHandler?

Such parameter could be a folder selected in the page.

I tried to change the url by setting the ctrl._handlerUrl attribute from various events. Does not work, the params are removed before they get to the handler.

Creating cookies might work but are no solution in my case.

I am wondering if I am the only person needing such a thing...? Please help!

Thanks,
Stephan

PS: There seems to be a bug when setting a handler url on server side with query string parameters. These parameters are then properly passed to the handler, however, the control adds a "?type=rau". It should of course have added "&type=rau".

Header widths don't match item widths with static headers

I see there are a ton of messages about column widths with static headers, and I think I've gone through all of them and tried all of the tricks to get the column headers to be the correct width, but so far nothing has worked for me. I have a radgrid in a tooltip (not sure if that matters, this seems to happen anywhere I use a radgrid) and have it set to UseStaticHeaders="True". I have the MasterTable layout set to "Fixed", and have all of the column widths specified, header and item. The column widths for the header DO NOT match the item widths. The item widths are correct. I have tried setting the layout to Auto and removing all of the column widths, same result. I am calling the client-side "repaint" method, no change. I'm really not sure what to do at this point. I'll attach a screenshot of what I get, but here's the code I am using in the aspx:

<telerik:RadGrid ID="radGridAssociates" EnableViewState="True" runat="server" AllowSorting="false"

I've also tried setting the MasterTable width to the same width as the RadGrid (548px), and setting it to 95%, which was another suggestion. None of these fixes have worked for me. Any help is appreciated!

Thanks,
Eddie

Exporting to pdf and conditionally change text colour depending on a column value

Hi

I am exporting a radgrid to pdf and setting the background colour of alternate lines as light grey, font and font size for cells and footer in the item created event, and all is working as it should.

However I would like to change the text color or background color of a column based on the value of another column but I am not sure in which event I should do this while exporting to pdf. I tried the RadGrid1_ItemDataBound event but it has no effect on the pdf output.

Can you point me in the right direction?

Thanks

Row alignment problem after zoom in / out

Hi,

I've been experiencing a problem with RadPivotGrid for a while now and the problem is when you zoom in (or out) a page that contains radpivotgrid, row alignment is gone and as you see in the attached screenshot, the problem exists even in product demos.

this also happens occasionally without even zooming, specially on slow connections rows are not aligned with their headers properly.

Is there a fix for it? Is there a client side method that can realign rows?

Please help.

Thanks
