How do you avoid file names with &, ', etc? If these are image files the browser chokes on them. We need to have them renamed during the upload. Nothing I am trying seems to work. I tried to simply copy the original file to the new name in the postback and that doesn't work either. I get an error that it cannot find the file.

Critical RadMenu Issue when trying to call via ajax

In a scenario, RadMenu is present in a user control. This user control is bind in the master page of the application. Hence all content pages have this menu. I need refresh only the RadMenu (not the entire page) from the content pages. I did wrap up the RadMenu with an updatepanel. So from my content page via Javasscript (I need to make the refresh via JS) when I am calling __doPostBack('updatepanel',''). The updatepanel gets call & it reloads it. Since the UserControl(having the RadMenu) is inside the UpdatePanel the same gets called & a postback is incurred in it. This calls the function responsible for populating the menu. However, this time it gives an exception :

Error: Microsoft
JScript runtime error: Sys.ArgumentTypeException: Object of type
'Telerik.Web.UI.RadMenu' cannot be converted to type 'Sys.UI.Control'.
Parameter
name: instance

Help:
- Need to overcome this error OR find a different way to handle the above scenario. Any immediate help would be great.

Radgrid loosing data on GridEditCommandColumn

Im very new at using Telerik so pleas bare with me.

ive been trying to follow this
http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/edit-form-types/defaultcs.aspx
Here's my problem, im using EditForms as Editmode of my Radgrid but the difference is that my radgrid has a child grid
but everytime I click on edit button on the child grid the child grid becomes missing, and will only show up again when I retract and expand again the parent grid, only then the editform together with the child rid is shown, but still the details of the child grid is gone, please see the attached image for a better picture of whats happening.

Picking up internal CSS styles from HTML document

Hi,

We use the editor for email marketing campaigns and sometime clients will have an email designed and the designer will set internal CSS styles within the HTML document. Is it possible for the editor to automatically pick up the internal CSS styles and set them in the CSS Class drop down box? I know it's possible to point this to an external CSS file but there is no mention of internal CSS styles.

Many thanks

"Request Not Available In This Context" error in design mode

Hi there;

I'm attempting to upgrade an older project that uses Q2 2009 to Q2 2014. However pages that contain RadScheduler have the above error instead of the control at design time. At runtime, nothing renders. Any ideas?

Thanks,
Jason

Repaint vs Rebind

Hi,

I was trying to find the differences between repaint and rebind client side function of radschedudler. I have a webservice bound scheduler and would like to refresh radscheduler to show latest resources(technicians and their appointments). Technician Timeslots and appointments are color coded based on some attributes.

Rebind fxn only updated the appointments but did not refresh scheduler timeslots.Repaint was helpful in refreshing the technician schedules showing latest color code. Is repaint fxn alone enough to achieve both objectives? Can someone point me to detail definition of these client side functions?

Thanks,
Prava

FormDecorator messes with box-sizing

Hi,

We found that RadFormdecorator overrules;

html {
box-sizing: border-box;
}

*,
*:before, *:after {

box-sizing: inherit;

}

Is it necessary to do this on such a high level?

Putting “
!important” tags in the css, resolves the matter.

weird close behavior

I have an image that has a rad tooltip attached to it. I'm having a weird behavior with how the tooltip closes. I don't know if there's a way to fix it or not. I wasn't sure how to set all the various properties, but I have tried different settings and nothing has fixed it. Here's the behavior:

- If I mouse over the image and then mouse directly off, the tooltip disappears immediately.

- If I mouse over the image and then move the mouse cursor over the tooltip window and then mouse out, the tooltip does NOT disappear immediately. It stays open for awhile and then closes. I would like the tooltip to disappear immediately.

Here's the code in my ASPX file:

<

asp:Image ID="imgRelationshipHelp" runat="server" ImageUrl="~/Images/help.jpg" CssClass="noPaddingOrMargins" />
