Here's what I'm trying to accomplish.

I have a div that contains a LinkButton and some text and I want to be able to open a context menu in the same location relative to that div (probably just open down from bottom center). I'd like this to happen preferably on mouseover and then close when the mouse leaves both that div and the context menu. I've been able to get the context menu to open relative to the mouse on mouseover but this isn't exactly what I'm trying to accomplish.

Thanks in advance,
Ben

Ignoring onClick showEvent during handling onMouseOver event

In our project, we've got a weppage with radgrid - one of its columns is templatecolumn with button inside. We're using onShow event set to "OnMouseOver" to displayo a tooltip. We noticed that some f our clients often click the button. When mouse starts to hover over the button but the tooltip isn't visible yet, they click the button which basically cancels the action of showing tooltip. It would be great if tooltip could ignore click on its parent in situation where it's already started to show due to onMouseOver action. Is it possible?

Is this a bug?

If you take the following code:

<telerik:Radslider id="slider2" runat="server" itemtype="Item" skin="Windows7" Height="40px">

<Items>

<telerik:RadSliderItem Value="1" Text="One" />

<telerik:RadSliderItem Value="2" Text="Two" />

<telerik:RadSliderItem Value="3" Text="Three" />

</Items>

</telerik:Radslider>

<script type="text/javascript">

$(document).ready(function()

{

$find('<%= slider2.ClientID %>').set_value(2);

});

</script>



and run it in a browser, it actually sets the slider to Item 3, not 2 as specified.

Is this a known issue or am I missing something here?

[Solved] ToolTip is gone after postback

Hello,

I have a treeview in a combobox.
When i select a node, the node's text appears in the combobox input field.
In additional i set node's text as a tooltip.

1. Why the first line in the next code snippest doesn't work? (No tooltip appears)

//This line doesn't work for some reason that i don't know.

//comboBox.ToolTip = args.get_node().get_text();

//This line work's perfect.

comboBox._element.title = args.get_node().get_text();

2. I added an asp button to the page, after i click the button there is a postback that causes to the tooltip to disapear.
How can i persist the tooltip?

Thanks,
Oren

Error: Specified argument was out of the range of valid values. Parameter name: ItemHierarchicalIndex trying to recreate a telerik demo solution

I realized I had posted this question in perhaps the wrong forum (here) so I am reposting here in hopes that someone might be able to answer this. Any help would be greatly appreciated!

I am trying to recreate functionality found in this demo from telerik.

When I attempt to drag and drop the available orders to shipped orders I receive an error:
Specified argument was out of the range of valid values. Parameter name: ItemHierarchicalIndex

I have modified very little from the default demo code. The only change I have made is the GetOrder routine. Here is my complete code:

GridCalculatedColumn not playing nicely with GridDateTimeColumn

I have the following 2 column definitions in a grid. When the grid displays there is no data in the DateTime column, but the calculated field is populated correctly.

If I delete the calculated column then the DateTime column works correctly.

What is wrong with the calculated column definition?

Mike

[Solved] RadEditor in RadWindow question

Hi,

I am implementing the RadEditor in RadWindow code example into my application. In your example you are only displaying one RadEditor that is on the Default.aspx page in the RadWindow. In my case I have 8 RadEditors on the same Default.aspx page and I need to display each of them in the same RadWindow, only one at a time of course. I will show you the code I am using below. Please assist.

        DefaultCS.aspx:

        function SetEditorContent(content)
{
$find("<%=MyRadEditorOnPage1.ClientID%>").set_html(content); //set content to RadEditor on the mane page from RadWindow
}

        EditorInWindow.aspx

        function setContent(content)
    {
     var editor = $find("<%= editor1.ClientID %>");
         if (editor) editor.set_html(content);
    }

How do I do this for MyRadEditorOnPage2 - 8? Would some kind of a switch() statment work?

Thanks,

Editor
