xyzGrid; Quicksearch, Columns with Dateformatter not properly searchable

Hi JaiQ,

John Ranger here again 😃

I have a grid where I have 3 columns (DateTime type in xyzRow.cs) where I have a dateformatter like this:

xyzColumns.cs

...
[DateFormatter(DisplayFormat = "yyyy-MM-dd HH:mm:ss")]
public DateTime TimestampStart { get; set; }

I would like now to be able to Quicksearch These visible Dates like “2016-02” or “2016-02-01” but it only allows me to search either for “2016” or “02” but I cannot Combine it like the above “2016-02”.

I tried with putting the dateformatter from the xyzColumns.cs to xyzRow.cs but without success.

Is this at all achievable and if yes, how would I do this? (I didn’t find a hint about this in the DEV-Guide)

Thanks for your help and

with Kind regards,

John

Yes, expression attribute and most other is close to SQL as possible. Just it might not be database agnostic but i’m planning to add something like Expression(“SqlServer”, “…”), Expression(“MySql”, “…”) etc to handle dialect specific cases.

Btw, this would probably be slow with big tables but you’re the database admin, so i suppose in that case you’ll come up with a calculated field and index on it.

Anyway glad to help, especially users who cares about helping others like you do 😉

To all wo reads this, I have solved the additional (hidden) quicksearch addon-fields like this (Suggestion of Volkan Ceylan):

In the xyzRow.cs, add a new stringfield like this:

        [DisplayName("Timestamp Job Generated"), Expression("convert(varchar(19),Timestamp_JobGenerated,120)"), QuickSearch]
        public String TimestampJobGenerated_search
        {
            get { return Fields.TimestampJobGenerated_search[this]; }
            set { Fields.TimestampJobGenerated_search[this] = value; }
        }

where the convert(varchar(19),Timestamp_JobGenerated,120) is the command which will be used within the resulting SQL query. Timestamp_JobGenerated is the SQL table field where the original datetime value is stored.

The resulting query in my case Looks like this (when I typed 2016-02-22 in the search box:):

DECLARE @p1 NVARCHAR(4000) = '%2016-02-22%';
DECLARE @p2 NVARCHAR(4000) = '%2016-02-22%';
DECLARE @p3 NVARCHAR(4000) = '%2016-02-22%';
DECLARE @p4 NVARCHAR(4000) = '%2016-02-22%';
DECLARE @p5 NVARCHAR(4000) = '%2016-02-22%';
DECLARE @p6 NVARCHAR(4000) = '%2016-02-22%';
DECLARE @p7 NVARCHAR(4000) = '%2016-02-22%';
DECLARE @p8 NVARCHAR(4000) = '%2016-02-22%';
DECLARE @p9 NVARCHAR(4000) = '%2016-02-22%';
DECLARE @p10 NVARCHAR(4000) = '%2016-02-22%';
DECLARE @p11 NVARCHAR(4000) = '%2016-02-22%';
