You should do this in a query window, not in some view or query designer. Stop using those. Please.
SELECT
ITR_EmployeeID,
CONVERT(DATE, ITR_TransDate) AS TransDate,
COUNT(ITR_TransType) AS TC
FROM dbo.ITR
WHERE (ITR_EmployeeID IN (N'sweda', N'bakja', N'gebwa'))
AND (ITR_TransType LIKE N'PO Inspect')
AND (ITR_TransDate >= @FromDate AND ITR_TransDate < DATEADD(DAY, 1, @ToDate))
GROUP BY ITR_EmployeeID, CONVERT(DATE, ITR_TransDate);
Get this query working with the right results in SQL Server Management Studio (again, in a query window, not the buggy visual designers). THEN get it working in whatever application code you're trying to implement it in, and deal with those issues separately (or create a stored procedure and avoid any problems you're having incorporating T-SQL query text into some other app).
