Trying to force a child grid into in-line edit mode based upong a rowclick on the client.

Using rowclick fires for the parent grid (really don't want that to happen) and I get a Javascript "Object Required" error when I click on the child grid row. The JS function I'm using looks like this:

<

script type="text/javascript">

function RowClick(sender, eventArgs) {

alert("Click on row instance: " + eventArgs.get_itemIndexHierarchical());

sender.get_masterTableView().editItem(eventArgs.get_itemIndexHierarchical());

}

</script>

How can I stop the click on the parent and actually have it not generate and start the in-line edit on the client?

Best practice for disabling javascript postback problem?

Hi Telerik,

So, I encountered the issue where I would change a RadComboBox's selection programmatically client-side and it would trigger a postback when unwanted.

I came up with this solution, but I do not know if this is best practice. If not, what other options do I have? If so, cheers to anyone else who can use it.

1) Turn RadComboBox autopostback to false.

<script type="text/javascript">

var doPostback = true;

function pageLoad() {

doPostback = false;

$find("<%= RadComboBox1.ClientID %>").findItemByValue("YourItemHere").select();

doPostback = true;

}

function OnClientSelectedIndexChanged(sender, eventArgs) {

if (doPostback) {

__doPostBack('RadComboBox1', '');

}

</script>

How can I fire a refresh when I select a row, but not fire the refresh for the rest of the events

I have a grid. When a "select"a row I fire a refresh of some of the panels in the webform. But when I move between the pages of the grid or order by one the columns, also the grid is firing the refresh of the panel.

How can I refresh the panel only when I "select" the row, and not for all the grid events.

Next

Return repertoires

End Function

End Class

My main problem occurs when I try to upload or create new folder on nodes deeper than 2

Example:
        Folder1                          Buttons (Upload and CreateNewFolder) enabled
                    -Folder2                          Buttons (Upload and CreateNewFolder) enabled
                    -Folder3                          Buttons (Upload and CreateNewFolder) enabled
                                    -Folder4                        Buttons (Upload and CreateNewFolder) disabled
                                    -Folder5                        Buttons (Upload and CreateNewFolder) disabled

JScript error with Visual Studio 2010 and framework 2.0

Hi,

We have migrate Visual Studio 2005 to Visual Studio 2010 recently but we have to keep the framework 2.0.
Now, we have some errors like "Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors."
The problem occur with Internet Explorer 8

We use RadControls for ASP.NET AJAX.

I will give you a specific example.
We have a master page with the script manager.
----------------------------------------------------
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true"></asp:ScriptManager>
----------------------------------------------------
In the content page, we use a ModalPopupExtender in a child page when a user click on a button into a list.
When the button is click, we receive the error "Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors."

Splitbar Tooltip Localisation

I have partially localized the splitbar tooltips. You will notice in my image attached the tooltip displays in Japanese except for the word "bottom" which is using the {0} variable to replace with bottom, top, left or right which pertains to the pane to collapse/expand.

Can you please tell me how I can gain access to that variable so I may have complete localization of the tooltip?
