Question

This article is really great and awesome. This is from the topic “ASP.NET MVC 2.0 Implementation of searching in jqgrid” – ASP.NET MVC 2.0 Implementation of searching in jqgrid.

But right now I was facing searching problem when I added a field with small integer data type. The field added with data type of small integer will serve as Status.
Lets say the value one(1) is for Active and value two(2) is for Inactive.

When I type 1 or 2 from the text box it was throwing an error of

System.Data.Entity: The argument types ‘Edm.Int16’ and ‘Edm.String’ are incompatible for this operation. Near equals expression, line 6, column 12.

Thank you in advance.

Answer 1

I am glad that my old answer was helpful for you. I suppose you have problem near the line

// TODO: Extend to other data types

In the code which I included in the answer I shown that propertyInfo.PropertyType.FullName hold the information about the datatype of the entity’s property. In the code I used only two types: string and 32-bit integer. In case of 32-bit integers I made the corresponding data parsing with respect of Int32.Parse:

String.Compare (propertyInfo.PropertyType.FullName,
                "System.Int32", StringComparison.Ordinal) == 0 ?
    new ObjectParameter ("p" + iParam, Int32.Parse(rule.data)

You should replace ” ? : ” operator with case where you test propertyInfo.PropertyType.FullName for more data types. For example in case of smallint SQL type you should use System.Int16, in case of tinyint it should be System.Byte, The sbyte SQL datatype corresponds to System.SByte and so on. If you would use as the second parameter of ObjectParameter correct datatype all should work correctly
