Questions on UI for ASP.NET AJAX Forum

Hi,

I have a DotNetNuke module with quite some controls being loaded dynamically. Each of the input controls has autopostback set. In practice, a user will tab to a next control.

In javascript, I put the ID of the newly focussed control in a hidden field.
Then autopostback occurs, and I use RadAjaxManager.FocusControl() to set the focus to the control in the hidden field.

This works just fine in FireFox and IE9, but doesn't work in IE7 (or IE9 with compatibility mode set to true).

Any ideas?

Thanks!

Ajax updating controls when it is not supposed to

Hi there,

I have a timer that updates a grid on a condition. For example:

if (IsDifferentFilter())

{

//Load logs method is called so the datagrid will be updated

Thread logsThread = new Thread(new ThreadStart(LoadLogs));

logsThread.Start();

logsThread.Join();

}

//else the datagrid will NOT be updated

The issue here is that even though the datagrid is NOT updated, it still gets refreshed. When I say refeshed i mean its just the datagrid not the whole page.

The grid is ajaxisfied using:

<telerik:RadAjaxManagerProxy ID="radAjaxManagerProxyLogs" runat="server" >

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="tmrAutoFilter">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="dgLogs" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="dgLogs">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="dgLogs" LoadingPanelID="ldgBar" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

Any help would be appreciated.

Thanks

K

Edited (Nov-21-2011): I realized the OnInit code is being triggered after each timer tick as well. That is not normal is it

problem with context menu and grouping in RadGrid

Hi there,

We're currently experiencing problems with our RadGrid when grouping a column it is causing us issue with the opening of the right click context menu.

The problem occurs if we have for example 3 "Groups" in our grid, we have all our groups collapsed by default, we expand the third, and then right click, it causes a javascript error, if we expand the very first group and right click, it works fine, but then the right clicks on the third group are "offset" ...

see the attached video for more info

Update caused theme to stop loading

I did a update of my trial version to v.2011.3.1115.40 from Visual Studio after which my project now refuses to load the project themes. What has this upgrade changed to cause this? Does it mess with folder permissions?

Unable to move docks

I am dynamically creating docks when a user clicks a button, inside the dock will be various controls depending on what "page widget" the user has selected from the dropdown list.

I have started off with the simplest "page widget", a RadEditor and a Textbox.

I can persist any data entered into the controls by saving it to a session and re-populate the various controls, however I need to be able to move the docks around so that the order of the "page widgets" can be changed easily but I've lost this functionality, I cannot move, collapse or remove them.

I have simplified the code down to the basics to make it easier to read.

Any ideas? Thanks

(I don't care about the docks open/close state, collapsing will be removed)

ASPX
