Hi Community,
Need help with the hide expand/collapse (buttontype="ImageButton"). I have look at the documentation page http://www.telerik.com/help/aspnet-ajax/grid-hide-expand-collapse-images-when-no-records.html, but it hide everything. Because the nestedView.Items.Count always equal to zero (Not sure if I'm doing it right).

I have an attachment column if they have an attachment it show the detail (detail table) about the attachment, when they don't have an attachment I want to hide the button or disable it.

Any help would be greatly appreciated it.

See attach image.

Browser exception while removing menu items using IE 10

Hello,

We've run into a fairly obscure but critical issue when removing menu items client-side using IE 10. This seems to be an IE 10-only bug - does not occur for other versions of IE or Chrome or Firefox I believe. If there is code like this:

var historyItems = historyMenu.get_items();
historyItems.removeAt(0);

and there is only one menu item in the list, IE 10 will throw an exception:

Error: NoModificationAllowedError

inside of Telerik script. This line:

if($telerik.isIE&&s){s.outerHTML="";

Call stack is:

_purgeEmptyGroup
_childRemoved
remove
removeAt

We're using the very latest Telerik release. 2012.3.1205.40

Please advise,

Thank you,

- Mike Oliver

item backColor overriding hover color

We changed our grid to assign an item Backcolor ( e.Item.BackColor = System.Drawing.Color.Red;) and now the hover color is gone. We do this on itemDataBound.

Before this change, hovering over each row would change the background.
We still have the client settings set: EnablePostBackOnRowClick="True" EnableRowHoverStyle="True"

is there a way so the BackColor does not override the hover, we just want to see the hover color again, I believe it defaulted to light blue.

Thanks

Create WebServiceSettings for RadAutoCompleteBox programmatically

Hi

I have a requirement to create a RadAutoCompleteBox programmatically.

I have successfully created the RadAutoCompleteBox via code but I am unsure how to set the TextSettings and WebServiceSettings programmatically.

The documentation describes a WebServiceSettings class but I am unsure if it can be used for RadAutoCompleteBox and how to use it.

I also see that a AutoCompleteBoxTextSettings class exists but I am also unsure if it can be used to set the selection mode.

Ultimately I want single selection and for the RadAutoCompleteBox to post back to the web service to get the detail to display.

Thanks.

[Solved] Error in ajax with grid and dropdown

Hi
In Sharepoint 2010 I created a web part with a dropdown that contain a list of the month and based on the selection some data is shown in a grid. If I don't ajaxify it, it works well. When I work with ajax , if I select first time imediately after the page is shown a month with no data, it show the grid empty, when I select back to a month that has data I get this error
"
Microsoft JScript runtime error: Sys.ArgumentUndefinedException: Value cannot be undefined.
Parameter name: type
".

If imediately after the page is shown I select a month with data and then a month without data and then a month with data i have no erorrs.

How I can fix the error ?

Thank you !
Hans

ContentFilters=None not working as expected

Hello,

Given this C# code:

HtmlContentEditor1.Content = @"<html><body>

<img height=""0"" width=""0"">

<a href=""http://www.telerik.com"" style=""color: #9a9a9a;"">Telerik</a><br>

</body></html>";

and this in the .aspx file:

<telerik:RadEditor runat="server" ID="HtmlContentEditor1"

EditModes="Html" Width="600" ContentFilters="None" />

we are seeing the HTML content get rewritten as:

<html><head></head><body>

<img width="0" height="0">

<a style="color: rgb(154, 154, 154);" href="http://www.telerik.com">Telerik</a><br>

</body></html>

and when the ContentFilters="None" property is removed altogether, the HTML content gets rewritten as:

<html>

<head>

</head>

<body>

<img alt="" width="0" height="0" />

<a href="http://www.telerik.com" style="color: #9a9a9a;">Telerik</a><br />

</body>

</html>

This is pretty unusual behaviour -- in the first case it reordered attributes and rewrote inline styles.... and in the second case it reordered attributes and added one in the <img> tag, but left the <a> tag alone.

The HTML rewriting only seems to happen when initializing the control after setting the Content property. If I paste content into the HTML tab, then post the control back to the server, the content is unaltered.

We'd like to be able to use RadEditor for a project but it is critical that the editor not change the HTML content at all. Is this possible?

I can provide a sample project but it's larger than the 2MB upload limit due to it including the controls DLL itself. Controls version is 2013.1.319.40.

Any insight into this issue would be appreciated, thanks.

Warren.
