Server-side validation on an Entity Framework required field (property) does not work!

Has anyone had issues getting server-side validation on an Entity Framework required field (property) to work? The data type is a string (nvarchar). Server-side validation for required fields of other data types WORK fine. Only string fields have issues. I get the following error on UpdateModel(obj); of my POST method within the controller. Exception Details: System.Data.ConstraintException: This property cannot be set to a  null value.Source Error: Line 4500:                OnTextChanging(value);Line 4501:                ReportPropertyChanging("Text");Line 4502:                _Text = StructuralObject.SetValidValue(value, false);Line 4503:                ReportPropertyChanged("Text");Line 4504:                OnTextChanged(); I've even tried data annotations like this but it seems to get ignored.     [MetadataType(typeof(ObjMD))]     public partial class Obj     {    

SharePoint 2007, Modify Tooltip Text in SharePoint forms: EditForm.aspx and NewForm.aspx

I have a list in SharePoint that was created awhile back.  The names assigned to some of the columns in the list are no longer relevant.  Due to existing code, the column names cannot be modified to reflect the preferred names.  I was able to change the lables assiciated with these fields within forms NewForm.aspx and EditForm.aspx.  All looks and works just fine except for when the curser lingers in one of these fields, the tooltip that appears contains the underlining (original...no longer relevant) column names.  This is confusing to the user since the name within the lable and the tooltip are different.  I would like a way to either disable the tooltip from displaying or to modify it to display a custom value.  Below is the code from behind the form as it appears in Sharepoint Designer.  I would appreciate some input on this. <SharePoint:FormField runat="server" id="ff11{$Pos}" ControlMode="Edit" FieldName="My_x0020_Field_x0020_Name" __designer:bind="{ddwrt:DataBind('u',concat('ff11',$Pos),'Value','ValueChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@My_x0020_Field_x0020_Name')}"/> <SharePoint:FieldDescription runat="server" id="ff11description{$Pos}" FieldName="My_x0020_Field_x0020_Name" ControlMode="Edit"/>

AJAX ComboBox - required field validator

Hi All, I want to put validation on a combobox to ensure user selects/enters a value. I've tried using a the standard required field validator which doesn't work. So I would like to do the validation using javascript/jquery. Not sure how to approach. When I look at how the combo box is rendered, it appears as a unordered html list. There is also a hidden field but this always seems to be set to 0. So is it possible to do this validation client side. I've read so many posts about this but I havn't got an answer yet. Am I on the wrong path here? Any ideas? Thanks

Field validation failure on not required/blank drop-down box


I have a column in my list that is based on the records in another SharePoint list. When I try to edit a record in Datasheet View, I frequently get the following validation rule failure message:

The text entered for Client Impacted isn't an item from the list. Select an item from the list, or enter text that matches one of the listed items.

Even though the column appears to be blank to the naked eye, when you double click in the column, it selects what appears to be a space character and when you hit the delete key, it now passes the validation rule. So, my assumption is that the validation rule is saying something like "Space character isn't in the list, so you can't save the record..." Here's what's odd. I do NOT get the same validation rule warning when I edit in standard view and I know for sure that the column has not been erroneously filled with a space character. Anyone have any idea what might be going on here?

Thanks in advance for your help.
