Enter key behavior in RadGrid GridTemplateColumn

Hello:

I am experiencing the following problem (I am using ASP.NET AJAX Q3 2010 NET40): I have a grid that uses template columns. When a row is in edit mode and I press the enter key in the textbox after editing the item, a new item is inserted. I wonder why this happens in the first place and what I can do to disable/avoid this behavior.

I have tried disabling automatic inserts, keyboard navigation, submit on enter but to no avail.

Any feedback is appreciated.
Thanks!

Candlestick Chart colors

I am using the candlestick chart in my .NET C# stock market app. As you can see from http://demos.telerik.com/aspnet-ajax/chart/examples/newfeatures/candlestick/defaultcs.aspx the ChartSeries.Appearance-FillStyle-MainColor only sets the background color of the items whose close was lower than the open. Items whose close was higher than the open seem to have a transparent fill. I need to set those to a color (I want green fill for up days and red for down days).

I thought I could do the following:

foreach (ChartSeriesItem item in RadChart1.Series[0].Items)

{

item.Appearance.FillStyle.MainColorOpacity = 255;

    item.Appearance.FillStyle.MainColor = item.YValue2 > item.YValue ? Color.Green : Color.Red;

}

But that doesn't build because even though the intellisense for MainColorOpacity says "gets or sets", Visual Studio tells me it's read only and it's stuck at "0" if close > open. How can I set a fill color on these items?

RadGrid - horizontal scroll bar - problem with IE

Hello,

I have a RadGrid with UseStaticHeaders=true.
When I scroll the horizontal scroll bar, the column headers are fixed but grid contents are scrolling.
This occurs when page is postback.

This occurs in IE. In firebox, it works fine, both headers and contents of grid are scrolling.
Any idea to solve this?

<body> 

    <form id="form1" runat="server">  

        <div> 

            <uc1:AjaxPanelUC ID="AjaxPanelUC1" runat="server" /> 

        </div>

OnGridCreated Event - Firing Sequence Changed?

I have some UserControls that were working fine for quite some time (years in fact). I have upgraded to a the latest (Q1 2012 release) of the controls and it no longer works correctly. They are user controls because I am loading them dynamically in a tab control/pageview control...

The part that is no longer working is that I am grabbing the toolbar that is positioned above the RadGrid and changing some of the buttons based on some user permissions in the OnGridCreated event handler. It can no longer find the RadToolbar control. If I place a button at the bottom of my control and try to find the RadToolbar at that point, it finds it. Which lead me to think that the OnGridCreated event is now firing before the RadToolbar has been created.

So, does anyone know if anything changed in this new version or even the one previous? I think it was fine in v.2011.1.519.35.

At design time, when RadGrid is in source view, properties are not shown in properties window

At design time, when RadGrid is in source view, properties are not shown in properties window.

Only when we switch to the Design view and press F4 (to view Properties Window) or right click on the control to View Propeties, the Properties window appears with a list of properties and events.

Thereafter things work fine even on switching to code view.

Is it a bug? Why dont i see the Properties in the Properties Window when i am in the source view for the first time. Why do i need to switch to design view to view the list of properties.

Kindly suggest.

Regards

Error locating dictionaries

Hi guys,

I'm currently getting the following error when attempting to use the RadSpellChecker in my website

Cannot read the configuration/dictionary language parameters!

Stack Trace:

[ArgumentException: Cannot read the configuration/dictionary language parameters!]

Telerik.Web.UI.SpellCheckHandlerNoSession.ProcessRequest(HttpContext context) +628

System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +100

System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75

The dictionaries are in the correct place /App_Data/RadSpell, although deleting that folder doesn't seem to make any difference, and I am not setting the dictionary path differently anywhere else, and even if I do set the Dictionary Path explicitly I get the same error. Can you help?

html tags in node text

I have two websites, both .net 4, both using telerik dll 2012.215.1.40, and they do not render treeview nodes with html tags the same way. See attached files - "goodtree" is the desired behavior. I added a plain unordered list in "badtree" for comparison to see if all of my code was affected (something web.config or app pool related), but it is only the treeview. I am stumped. How can I get "badtree" to render the html instead of printing out the tags?
