Null Filter Object reference not set to an instance of an object

Hi All,

I have a basic RadGrid with GridDateTimeColumns and GridBoundColumns. Unfortunately, when I try to filter these columns I receive an "Object reference not set to an instance of an object." error. Reading the remainder of the error message, it appears that it is a "NullReferenceException." These columns do have empty (null) values, so I believe the error stems from this.

Can anyone please tell me how I can go about fixing this error?

Thanks,
Mark

RADSchedulerRecurranceEditor Layout Issue

I am using the RecurranceEditor control on a custom DNN 6.x module. I have the editor displaying on the screen, however the layout when selecting Weekly or Monthly is off a bit. It seems like the container is not wide enough for the controls causing them to wrap? Changing the width of the ediior did not help. I've attached images to show you where the wrapping is occuring.

EnableClientFiltering with dynamic loaded AutoCompleteBox

I have an autocomplete box wich is loaded dynamically inside a RadGrid nestedviewtemplate. It seems that in this scenario the "EnableClientFiltering" property set to true won't work and always provide an empty dropdown

<telerik:RadAutoCompleteBox runat="server" ID="ProvinciaId" AllowCustomText="false" MaxLength="80"

EmptyMessage="Provincia di nascita" CssClass="span3" DataSourceID="SqlDataSource1" DataValueField="ProvinciaId" DataTextField="ProvinciaName" Filter="StartsWith" IsCaseSensitive="false"

DropDownHeight="250" TextSettings-SelectionMode="Single" TokensSettings-AllowTokenEditing="false" AllowCustomEntry="false" InputType="Text" EnableClientFiltering="true" />

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:EvaConnection %>"

ProviderName="System.Data.SqlClient" SelectCommand="SELECT [ProvinciaId], [ProvinciaName] FROM [EVA_Province] ORDER BY [ProvinciaName] ASC">

</asp:SqlDataSource>

Any hint on how to overcome the issue?

Decorated DropDownList control doesn't render sometimes

Hi,

We have a form in asp.net 4 webforms application, this page has 30-40 (approx) fields and a mixture of default and telerik contrtols. And I use RadFormDecorator in our master page for consistent appearance. The problem is QA reported that sometimes some dropdowns does not "appear" ( render ) I have seen this happening sometimes on my localhost, too. The common workaround for us is to right click anywhere on web page and to click refresh to reload the radtab. No JavaScript error from F12 tools from my IE10 though.

Thanks,
-Aarsh

RadComboBox dropdown shows in corner on page load

I have my combo box inside a user control in multipage in a RadGrid nestedview template. So it's loaded dynamically on row expand AND it doesn't show up immediatly since it's on page 2 of the multipage.
When I expand the grid row and all the user controls inside the multipage (for each page) are loaded, the dropdown of the RadComboBox shows up in upper-left corner of the page.
If tried with OnClientLoad="(function(sender, e) { if (sender.get_dropDownVisible()) sender.hideDropDown(); })" and this works BUT doesn't prevent the dropdown to show up for about 1 second, which is awful... Any suggestion?
Thanks

RadEditor and radscheduler exception with hyperlink manager

Hello I have my own appointment add form. Basically a begin date,an end date and a RadEditor for the subject. In the rad editor I want to make hyperlinks. Suppose the appointment is for 2/10/2014 and the subject would be to assemble at a special address(i would google map the address and add that link in the rad editor)(Ex the subject of the appointment could be "Click here to see the location", where "here" would be a hyperlink.
When I add the appointment it should read as "Click here to see the location" without any anchor tags. I am attaching an image here. Please see how the appointment shows up as. Also while adding it adds correctly. Now while editing the appointment, when I make my changes it yellow screens with this exception

System.Web.HttpRequestValidationException: A potentially dangerous Request.Form value was detected from the client

What should i do to make it show up without the anchor tags and to avoid the above exception. If you need more information,please ask.Thanks
