Input fields not available after postback
Hi,

I have a strange issue.  I'm using masterpages and contentplaceholders.  I have a page where I have the RadAjaxManagerProxy with a LoadingPanel.
On the page there are several object, input field, dropdown, RadDatePicker, RadEditor, DataGrid, buttons,...
When I had a postback from for example pressing a button, I have a strange situation.
Let's say I push a button to add data from fields to the datagrid, after postback I select another value in a dropdownlist and then want to input data in the RadEditor.  The RadEditor is not available at that moment, I cannot click in it with my cursor, also all the other input field are not available.  Dropdowns, buttons, lists are available and can be changed but no input or Editor field.

Any Idea what the problem may be?

I cannot provide a link to the site because it is on our intranet.Also cannot copy the aspx file and master file because it is too hugh...

Kind regards

Skin not showing correctly - IE 9
I'm seeing some weird display behavior using a ListView with a data pager on IE 9.  I've already told the clients they need to upgrade their browsers but not all of them will :)

Anyway, I've attached a PNG of what I see (unfortunately not ALL the time).  The IE 9 F12 dev tools are horrible so I can't tell from those if a style sheet isn't loading correctly or what.

This is a scenario where I have a RadWindow which contains a RadTabStrip.  The tabs' content in the strip are dynamically loaded via ASCX controls.

I'm curious if others have seen this behavior with IE 9, and if they were able to eliminate it.

Scheduler Time Line View
Hello,

I'm creating a web application for a reservation system where i'm using the RadScheduler control in my page for managing all the reservations where the advanced form is being used to handle the insert and edit functionality.

Upon client request, I implemented the TimeLine view with resources being displayed at the left side of the control. Here a serious problem showed up where I was unable to create a new reservation in the timeline view by dragging the mouse over the time slots for selecting a specified period of time to be bind to the advanced form. When a double click is done the advanced form is called and the time shown in it is the duration of the slot (15 minutes).

I need to know how to implement this functionality in the time line view (time slot selection before insert like in Day view).

Thanks in advance.
Regards.
Scheduler

HtmlChart Default Width and Height Change in Q1 2015 Beta/Q1 2015
Since Q1 2015 Beta/Q1 2015 the default dimensions of the SVG rendering element in RadHtmlChart have changed from pixels to percentages (i.e., width="100%" and height="100%").

The actual RadHtmlChart dimensions are now defined by its wrapper and default height of 400px.

The change may affect the appearance of a chart that has no dimensions defined which is placed inside a div element with inline-block style and no width.

RadAutoCompleteBox and very large SQL table
I have a SQL Server table with over 2 million rows.  It's well optimized and I have a stored procedure that, given the start of a word, can return 10 matching records very quickly.  However, I'm trying to see if this can be used via the RadAutoCompleteBox. 

My test page is not loading (no error but it's taking forever to load) and I am assuming this is because it's trying to look at ALL 2 million records?

<telerik:RadAutoCompleteBox runat="server" ID="RadAutoCompleteBox1" InputType="Text"
                DataSourceID="SqlDataSource1" DataTextField="Title" Filter="StartsWith">
</telerik:RadAutoCompleteBox>
 
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
   ConnectionString="<%$ ConnectionStrings:MyConnectionString%>"
   SelectCommand="SELECT Title FROM dbo.AllKeywords ORDER BY Title">
</asp:SqlDataSource>

Am I doing something wrong?  Does anyone have experience in using RadAutoCompleteBox on very large data sets?

Enable / Disable Rad Grid
Dear Friends,
I created RadGrid with Enabled = "false". The grid got disabled.

Now i want to enable Grid cells when Edit Button click through Javascript.

I tried Like this

<ClientEvents OnBatchEditOpened="OnBatchEditOpened" />

//Enable/Disable Grid cell
function OnBatchEditOpened(sender, args)
{   
    if(EventID=="EDIT") 
        args.get_cell().getElementsByTagName("input")[0].disabled = false;
}

but the grid and cells are not enabling.

How to Enable ? Or what is wrong in this code.

Regards,
Rajendran
