Excel export: The file you are trying to open, '[filename]', is in a different format than specified by the file extension

Hello!

When I'm exporting to Excel (HTML or ExcelML) and when I'm opening exported file I'm getting this error/notification:

    
            "The file you are trying to open, '[filename]', is in a different
            format than specified by the file extension. Verify that the file is
            not corrupted and is from a trusted source before opening the file. Do
            you want to open the file now?"  (Yes | No | Help)

Is there any workaround (without changing registry/excel settings) for this to make excel not showing this question?

Thanks

EDIT: Ok. I've found solution for my problem here:

Hiding the Expand in the grid

I have a hierarchical grid that I have been implementing security on.

What I have done is limit the user to see only data they are allowed to see. So in the databind I skip over it if the user does not have access to that level of detail. I would also like to remove the expand if they dont have access to the detailed info. Anyway to do that?

Hide/Show Certain RadGrid Context Menu Items

Hi there, I have a context menu showing when the radgrid is right clicked which displays options "email user", "email mass users", "email users who have finished".

I have a radgrid which is populated with data which shows whether users have started or not started their courses. I have a column called "HasStarted" which displays false and true depending on whether or not they have started. When I right click on a row which has "HasStarted" as false I want "email user", "email mass users" to appear in the context menu and when I click on a row which has "HasStarted" as true I want "email users who have finished" to only appear in the context menu. The context menu works and the items run the correct cases just not sure how to hide and show certain items depending on the item clicked on. Any help will be appreciated thanks.

Strange behaviour on column resize

hi,
I'm making some test on your ajax grid and I've found it great but I've found an annoying problem regarding column resize.

This problem is present in your demo as well so you can easly verify it.
Go to http://demos.telerik.com/aspnet-ajax/grid/examples/client/resizing/defaultcs.aspx

Try to resize column by clicking between "Address" and "Postal Code", all columns width are affected by this action and their width change.
Please let me know if there is a way to work around this behaviour.

thanks a lot for your help

Custom Filtering for Template Column

Hi,

I have a Rad Grid control that is bound to a data source which has objects in it.
I use the object properties to feed the template in the template columns.

Please show me how can I implement custom filtering, which events do I need to handle ?
I need a way from which I can use the object and then decided if this row should be filtered or not.
The out of the box filtering is not going to work for my case.

I cant find any examples, please help.

Thanks
Karan

form within form - Ajax?

I am not sure if it is an Ajax-specific problem, or, just a Rad script issue... but, if I have a form inside the default page form, Telerik controls do not seem to work (it throws an error). If I remove this sub form, things work.

Here is sample code:

<%@ Page Language="VB" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="current_sswdc._Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

}

// end -->

Protected Sub rdpDateToView_SelectedDateChanged(sender As Object, e As Telerik.Web.UI.Calendar.SelectedDateChangedEventArgs) Handles rdpDateToView.SelectedDateChanged

lblDatePicked.Text = e.NewDate.ToString

End Sub

End Class

So - the PayPal forms are what break this. I cannot find a way around having the PayPal forms - somehow, I have to be able to use forms inside the main page form. Does anyone have some insight as to how I can resolve this conflict?

Thanks.

Show reminder window at regular interval with a list of appointments at regular interval

Hi,

Appointments in a scheduler has an attribute "state" that can be modified by the user. The appointment state transitions to 5-6 states.
I would like to display all those appointments that are in state 4 and state5 in Reminder window at 8:00 clock, 12:00 Clock and 4 :00 Clock.
I would like to display all appointments that are in state1 and state 2 in Reminder Window at 10:00 clock, 12:00 Clock and 3:00 clock.

Is this possible, if yes how can I achieve above objective?

Thanks,
Prava
