I have added my RadDateTimePicker to a asp:Repeater. on first load the data binding will be empty and this cause the error Value of '1/1/0001 12:00:00 AM' is not valid for 'SelectedDate'. 'SelectedDate' should be between 'MinDate' and 'MaxDate'

i would like to know how to i set the selecteddate to empty string or null value.

04. </HeaderTemplate>

05. <FooterTemplate>

06. </table>

Inner Text From Header

I'm trying to access the InnerText for a header on the website I am testing, but I'm not able to get the string. It keeps telling me that there isn't a definition for InnerText. I previously used InnerText to get the text from a Span - is there another keyword or, rather, how would i go about doing this??

Thank you,

M

Adding spreadsheet changes menu styling?

Hi,

I had a page that uses radmenu and it works just fine with the metro theme. As soon as I add a RadSpreadsheet control to my form then the styling of the menu goes haywire (colour is different, text is black instead of white), remove the spreadsheet control and all is back to normal again. What could cause this?

NumberFormat including the character 'n'

Hi,

I'm having some issues with the number format of RadNumericTextBox. If I for example want the NumberFormat-PositivePattern to be "n tons" and set the value to 123 the control's text gets rendered by the server as "123 to123s".

If I go to the field and then switch the focus to another field the javascript side of the formatting corrects the text to "123 tons".

If I use "tons n" as the format, the server renders "to123s 123" and the javascript renders "to123s n".

Clearly the server and client code are interpreting my format differently. So the bottom line seems to be that the server switches all occurences of 'n' to the value while the javascript switches only the first occurence of 'n' to the value.

I actually think the server does the correct thing (at least compared to the javascript). I think that the n in tons should be escaped by me somehow, but I can't find any mentioning of that in the manuals. The only thing I find is this text:

"The characters other than n in a formatting pattern are literal symbols. If you use the dollar sign ("$") as a currency symbol, for example, currency values are formatted using that symbol regardless of the value of the Culture property."

Could you spread some light on this issue?

Regards,
Martin

{

string filePath = (sender as LinkButton).CommandArgument;

Response.ContentType = ContentType;

Response.AppendHeader("Content-Disposition", "attachment; filename=" + Path.GetFileName(filePath));

Response.WriteFile(filePath);

Response.End();

}

I am still unable to get the file to download.

I have tried the following as well, but I still couldn't get the file to download - Download File From Grid Column

I also reviewed this demo - Column Types in Grid

Any help would be greatly appreciated.

Thanks,

Performance and size issue while saving data from client side

Hi team,

I am trying to save more records from telerik Ajax grid from client side.

1) "grid.get_batchEditingManager().saveChanges(grid.get_masterTableView());" this line is taking more time in IE and taking less time in chrome.

2) If i am trying to save more rows then it is not hitting WCF service method. It is showing timeout error in javascript and not hitting WCF service method. If am saving less records then it is hitting WCF service method and saving but problem with more records only.

Please help me in resolving these two issue.
