[Solved] Excel like filtering null values in column cause ArgumentNullException

This was working before, but now when there are null values in a column we cannot use excel like filtering. I don't think anything changed on our end. When I click the filter icon in the column header I get this exception:

System.ArgumentNullException was unhandled

HResult=-2147467261

Message=Key cannot be null.

Parameter name: key

ParamName=key

Source=mscorlib

[Solved] SQL Server nvarchar and unicode

Hi guys,

I have this case: I import a fUTF-8 without BOM file that contains translations of several languages.

My application import using T-SQL command INSERT BULK with DATAFILETYPE = 'widechar' (It needs to import Unicode format)

sql = $

"BULK INSERT CaptionFlat FROM '{OpenFileDialog.FileName}' WITH (DATAFILETYPE ='widechar', FIELDTERMINATOR =':',ROWTERMINATOR = '\n')"

;

Afterthat It keeps several operation and INSERT into other table that have a nvarchar field that will contain translation.

This table it will shows by RadGridView with this code

conn = new SqlConnection(Settings.Default.RTK2ConnectionString);

sql = "SELECT CBase.[Key] [Key],\n" +

"CBase.[Value] Base,\n" +

$

"ISNULL((SELECT [Value] FROM [Captions] WHERE [NAVKey] = CBase.[NAVKey] AND [LanguageID] = {LanguageToTranslateComboBox.SelectedValue}),'[Blank]') ToTranslate\n"

+

"FROM [Captions] CBase\n" +

"WHERE CBase.[IsCaption] = 1\n" +

$"AND CBase.LanguageID = {LanguageBaseComboBox.SelectedValue}";

cmd = new SqlCommand(sql, conn);

da = new SqlDataAdapter(cmd);

dtCaptions = new DataTable("Captions");

da.Fill(dtCaptions);

CaptionsRadGridView.DataSource = dtCaptions;

var obj = new ConditionalFormattingObject("BlankTranslation", ConditionTypes.Equal, "[Blank]", "", true);

obj.CellForeColor = Color.Black;

obj.RowBackColor = Color.LightCoral;

CaptionsRadGridView.Columns["ToTranslateColumn"].ConditionalFormattingObjectList.Add(obj);

CaptionsRadGridView.BestFitColumns(Telerik.WinControls.UI.BestFitColumnMode.DisplayedDataCells);

conn.Close();

I attach the effects, where the last column shows an error.

The label in language in original file is (for example DE language) "Rack-Jobben (nur für Italien)" but in RadGrid it shows "Rack-Jobben (nur f├╝r Italien)".

Can you help me to understand waher I wrong?

Changing Cursor is not Working on some Controls

Hi

I have a problem with changing form's Cursor, I have set a major cursor all over the form. It works fine every where.
But I have found some areas that cursor will change into windows default cursor.

- On SubMenus of Drop Down Objects
- On Start Menu of Rad Ribbon Bar

Where is the problem?
Why does cursor change into windows default as long as I have set a major cursor for the whole form?

I have attached an image for more detailed information.
