Export to Excel producing corrupted file

Hi,

I've been working with the RadGrid and exporttoexcel(). Originally, I didn't like the warning about the file format and extensions don't match message so I tried using biff file format instead and got the error attached.
I noticed there was another thread on this issue here. I ran the code provided and was not able to reproduce the file corruption error.

Any insight as to why I am getting corrupted files would be great,

Thanks,
Ian

RadHtmlChart make legend visible client side

Hi,

I am following this article:

http://www.telerik.com/community/code-library/aspnet-ajax/html-chart/exporting-radhtmlchart-to-png-and-pdf.aspx

To export my radhtmlchart to PDF. The problem is that I am hiding the RadHtmlChart Legend and displaying my own custom legend. When I export the chart I see the chart in PDF but no legend (understandbly because I am hiding the legend).

I believe that a possible solution could be that I make the Legend visible, then generate the SVG text, then hide the legend. Is this possible? Can you suggest a work around?

Which control should I go with to display an XML document in the browser?

I have an XML document that I wish to display in the browser. The sections of the document must be collapsible / expandable (similar to what IE does with an XMl document).

Which control should I use? The XML Document is not an actual XML file, it is an in memory XmlDocument represented by the XMLDocument class. How can I display this in my browser?

Upload by dropping riled into grid row.

subject must be Upload by dropping files into grid row.

hi friends,

sorry for posting same question here as I could not decide where it belongs. (admins, please don't get me mad :)

I want to upload image files by dropping them to grid rows.

imagine a product list and customer will drag and drop product images from computer to row that belongs that product. I don't want my client to enter edit mode, upload file and close edit mode, etc..

my client can upload multiple files for each row (product) and then I'll analyze and organize images at code side.

any suggestions ?

[Solved] Removing extra space in radnumerictextbox

Hi All,
How can I remove extra space in my radnumerictextbox. Whenever I change the width of the textbox it only applies to my textbox but there still about 80px of space after the spinbuttons. I am adding an imagebutton beside it but then it has huge gap between the spinbuttons and the icon and it doesnt look good. Heres the code. Thanks in advance.

<telerik:RadNumericTextBox ID="rntNumber" ShowSpinButtons="true" Width="50px" MaxLength="3" runat="server" Value="50" MinValue="10" MaxValue="200" NumberFormat-DecimalDigits="0">

</telerik:RadNumericTextBox>

<asp:ImageButton ID="infoBtn" runat="server" width="20px" height="20px" BorderWidth="0px" ImageUrl="../Images/Info.gif" />
