Is there any way to override the icon displayed for a file? I'm using a custom file browser provider which works fine, but the files aren't really files, they're items in my database, and their names have no file extension, and I don't want to add one just to get an icon to appear. How would I display my own icon for files?

I have a radgrid with about 18 columns, I've tried the basic code on this site that rips out all the html data and simply prints it, but it doesn't work well as in portrait, columns are cut off, and landscape fares only slightly better.
What would be the more efficient way to print out the radgrid (Ideally so it automatically formats the printout to fit all the data without cutting data out).?
Thanks in advance for your time.

We currently have a "window" that we would like to display our charts in and can't seem to get the chart to fit nicely in it (as depicted in image).
Window is 400 px x 400 px; there seems to be additional padding around the chart? Would like to remove the scrollbars. Any suggestions?

I have a Telerik RadHtmlChart inside an asp Panel which uses an ajaxtoolkit CollapsiblePanelExtender.
If the panel is collapsed when I assign a datasource to the chart and databind, after the panel expands the chart only fills 1/2 the panel size, left to right. If I have the panel expanded and the chart visible during the databind, it fills the panel all the way across as expected.
Somehow I need to know when the panel has expanded and tell the chart to resize/repaint and fill the available space in the panel, but so far no joy doing this.Or maybe there is a flag/property on my controls I've missed which would help the chart fill the available space even when the panel is expanded.
I would prefer to work in the C# code behind, but javascript/jquery solutions are also appreciated.Thanks,

Hello,
I have below code and when I drag groups to the groupingbar the grid shows me the group totals in the groupfooter. However when I export the grid to ExcelML, the grouping structure is there, but the groupfooters with their totals are lost. I have read several suggestions through using the OnExcelMLExportRowCreated and OnExcelMLExportStylesCreated to get what I want, but somehow I can't get it to work. Could you point me in the right direction?

In my radgrid, on click of AddNewRecord, I open a user control with a search textbox and button. To hide the AddNewRecordButton and Header I have on RadGrid1_ItemCommand I have the following:
But when the search textbox retrieves results and I select one of the entries, a postback is done to display the selected the value, after which the header and AddNewRecordButton are again visible though, the user control is still open. Is there a way to hide it after the postback?
if (e.CommandName == RadGrid.InitInsertCommandName)
{
this._RadGrid1.MasterTableView.CommandItemSettings.ShowAddNewRecordButton = false;
this._RadGrid1.MasterTableView.ShowHeader = false;
}

I have a grid with a GridClientSelect column. Clicking anywhere in the row other than the checkbox for that row causes all other selected/checked rows to deselect. How do I stop this. I want the row to only be selected by clicking the checkbox. I have shown in attached screenshots.

Hi,
I have a quick question.
I'm trying to implement the RadGrid in BatchEdit mode.
I need to customise validation on some fields, and to do so I need to 'wire up' the event behind 'Add new record' button embedded on the grid.
E.g. the user added a new row/record and before adding another one I need to validate the added data.
I'm able to capture the events behind the 'Save changes' and 'Cancel changes' grid buttons but haven't been able to track down the 'Add new record'.
What are the client side and server side events behind this button?
Thank you in advance.
