Displaying error messages on grid load

[Boone]

I have a web service that returns me results as this data structure.

public class LoadSearchingReturn

{

    [DataMember]

    public IEnumerable<Results> SearchingResults { get; set; }

    [DataMember]

    public IEnumerable<string> Errors {get;set;}

    [DataMember]

    public int TotalResults { get; set; }

}

TheSearchingResults is what displays in my grid and I use the Total Results inside my schema like:

dataSource: {

    schema: {

        data: "d.SearchingResults",

        total: function (data) {

            return data.d.TotalResults;

        }

    },

So, my question...How do i access that Errors collection and display that to the user?

Hello Boone,

I am not sure if I completely understood your scenario. How do you want to display the Errors collection to the user - as a grid column or as a side information?

The dataSource works with a single array of objects and you cannot pass both "d.SearchingResults" and "d.Errors" to it. As a workaround I would suggest to define the data parameter as a function and access the Errors collection before the Json data is processed.

In this demo page you will find an example that uses the aforementioned approach in action.
I hope this helps.
