Hi!

   I have a radGridView, which has export to word command each row, however, I need to format the data, so I build the data I want as html string.

When the user click on the export to word command, I will take the DataKey to get the data and export to word document, on UI, it will popup to ask the to

open, saveAs or cancel (as we usual see for downloading command). 

I have tried almost all of the sample code I could search from Google, it worked if it's a single button not inside the telerik:radGridView, once I tried within

telerik:radGridView, it always return a "Sys.webForms.PageRequestManagerParserErrorException" without much help message.  UI sample as attached file.

Could I get a sample code for my case? Thank you in advanced!

Hi

When using a combobox that has a client item template ("#= Nme ## if(!Ena){# <span class=""disabled""> (disabled)</span> #}#") I find that when checkboxes are enabled the checkbox appears on the line above the template text.  I have tried using the nowrap method along with white-space and word-break styles with no luck.

The online demos shows each modes independantly but not having seen them together I don't know if this is my code or a fundamental issue with the control.  Any ideas for a fix?

Regards

Jon

When re-creating a dynamic wizard in user control The active step is not reset to 0 with:

rw.WizardSteps.Clear()

How can I achieve a reset of the active step?

Hi,

I have a radgrid with scrolling enabled and static headers. Everything works perfect. However, the issue im faced with is when I click edit, I need to scroll down to get to the edit portion and after saving or cancelling, the scroll position is saved on the LAST scroll position, which means that the scroll position will now be way lower than it was when I clicked edit. I hope this makes sense.

All I want to do, is save the scroll position when I clicked edit, so that once updated or cancelled, that it will go back to that scroll position. 

Please could you help ?

Thank you

Still in beginner phase of radscheduler use/knowledge

local testing opens the radscheduler as expected, but as I try the export to pdf  , using

  protected void RadButton1_Click(object sender, EventArgs e)
   {
            
            RadScheduler1.ExportToPdf();
   }

get this error on localhost

I am working on an web page that uses the RadTabStrip, RadTab,RadMultiPage, and RadPageView objects.

There are four tabs. The first three tabs contain various RadText, RadDropDownList, and RadListBox objects for the user to enter information. On the first page, when the user enters an ID number, a server call populates information currently on file for that number. That works without any issues. 

My problem is when the third tab is selected, I need to call a server routine that will use information entered from the first two tabs to populate the RadDropDownList and RadListBox objects on that page. The code I have written is being executed, but when it returns, the third tab is not selected and the page view of that tab is not displayed. Instead you still see the last tab that was active. In addition if the last tab was tab one, then clicking on tab two results in tab two being displayed and the contents of tab one being displayed under it.

I am calling my routine from the OnTabClick event of the RadTabStrip:

but it did not appear to have any effect.

I am hoping there is just some type of render call that I am missing.

I've got a customer who is reporting that occasionally when exporting from the grid (and then opening the file directly rather than saving it), they receive an error message box from Excel, "Unable to read file."

I have been unable to reproduce the issue, and it doesn't happen every time for them either. Any thoughts on what could be causing this?
