I'm having an issue embedding a RadMenu within a RadGrid cell. Its within a TemplateColumn and binds correctly through the ItemDatabound event, but there's something off on the rendering.
I've got scrolling enabled, but the RadMenus render past the defined boundaries of the RadGrid. The same effect can be seen by adding standard ASP Button controls instead. I changed the RadGrid back to the RadControls ASP.NET Q1-2008 as a fix for now.. is there a fix for this?

I am trying to show and image only on row mouse over. and once the row is click(as stated above), keep this picture showing. onrowmouseout, the image would disappear. Not just mousing over the image, but mouse over the row. Any help would be greatly appreciated.
Thanks for you help.

I'm using a combobox with telerik skin for filtering in my radgrid. Using IE 7, each combobox shows vertical & hortizonal scrollbars whether they are necessary or not. I am setting the dropdownlistwidth property that should ensure my users don't have to scroll - the horizontal scroll shows up no matter what. Also, the vertical scroll always shows up always hiding the last item in the list - even when the list only has 2 items.
The same code works perfectly in FF, so I'm sure it's a css problem in the skin. I've tried a few other skins in IE and still get the weird scrolling. Any chance this is any easy fix in the css? I plan to create a custom skin so hopefully this is an easy item to address.

Hi,
I'm using(amended) the Grid to grid drag n drop solution for a Folder browser, "file copy" from one folder to another,
The problem I have is
when
The above alert does not fire
...
...
...
....mouseUpHandler..
...
this shows radGridOver =""
I'm using(amended) the Grid to grid drag n drop solution for a Folder browser, "file copy" from one folder to another,
The problem I have is
when
mouseUpHandler event in dragdro.js fires,
the radGridOver var is empty, so no Ajax postback.
I tracked it to the mouseOverHandler(var mouseOverHandler = function(e))
and after the check for IE it seems to exit, as the debug window.alert does not fire..
I am using IE 7, and the demo project does run and swap grid rows,..code is identical(cut n pasted),
var mouseOverHandler = function(e)
{
if (!e)
var e = window.event;
var parentEl;
if(e.srcElement) //IE{
//debug
window.alert("ParentE1 = " + parentEl.id);
The above alert does not fire
...
...
...
....mouseUpHandler..
...
this shows radGridOver =""
if
(radGridOver != "" && radGridOver != movedRow.Owner.OwnerID) {
//debug
window.alert(
"radGridover - ajax call");
//
var ajaxPanel = window["RadAjaxPanel1"]; ajaxPanel.AjaxRequestWithTarget(eventTarget, eventArgument);
}
I am at a loss now,..C# and js seem to be accurate word for word
Attached is the form
TIA
Neal

Hi,
I've noticed an intermittant problem with RadEditor in IE7, namely that quite often, when the RadEditor is loaded, the toolbars don't display - you just see the left-hand edge of each toolbar but no buttons etc.
Sometimes a refresh will sort this, but other times you have to close the browser and re-open it and try again.
I don't see this problem in Firefos or Opera or Safari.
Anybody else had this?
Thanks,
Matt

Hi,
In Prometheus RadEditor, where I use Image manager tool, I randomly get an error, where in Image Upload dialog box I'm not getting the upload button itself. It's just not there. What I've noticed is, that when I move the dialog box (dragging it a bit on the screen and then releasing it) the upload button appears (along with cancel link).
Is there some way how to work around this random misbehaviour, please?
Thanks
Adrian

hi
i just found out that the rad controls behave differently with each different browser. By far, firefox works perfectly.
While using IE 6, not too bad, just that sometime you can see the whole page is refresh when you know that the page has ajax enable. IE7 is the worst, every page refreshes and also the gird does not work well with IE7. Are there any way i can overcome the IE7 issues? Thanks

Hi
I have a web form with a button to show a modal window. I was able to move the window by dragging the window's title bar up above the content area of the IE browser so the title bar is hidden so I cannot grab it to move it back. Is there a way to prevent this?
Thank you,
Vincent
