handling error on grid add/update

[Kristin]

I am working on adding and editing items on my grid and occasionally I will get an error back from the server if there is a problem with the submission (i.e. username already exists, etc.).  I would like to handle this error gracefully and let the user re-edit the line and re-submit the changes.  Right now, it just looks like it changes in the grid but it doesn't actually update.

Here is what I have:

$("#tblCompanies").kendoGrid({

    dataSource: new kendo.data.DataSource({

        type: "json",

        transport: {

            read: {

                url: "http://192.168.1.33:8090/pumpSystem/getProdCompanyList",

                dataType: "json",

                type: "GET"

            },

            update: {

                url: "http://192.168.1.33:8090/pumpSystem/updateProductionCompany",

                dataType: "json",

                type: "POST"

            },

            create: {

                url: "http://192.168.1.33:8090/pumpSystem/addProductionCompany",

                dataType: "json",

                type: "POST"

            }

        },

        schema: {

            model: {

                id: "Id",

                fields: {

                    Id: { type: "number", editable: false },

                    CompanyId: { type: "number", validation: { required: true, min: 1} },

                    Name: { type: "string", validation: { required: true} },

                    isEnabled: { type: "boolean" }

                }

            }

        }

 

    }),

    columns: [

        { field: "CompanyId", title: "CompanyID", width: "60px" },

        { field: "Name", title: "Name", width: "150px" },

        { field: "isEnabled", title: "Enabled", width: "60px" },

        { command: ["edit"], width: "150px" }

    ],

    editable: "inline",

    toolbar: ["create"]

 

});

If there is an error on the add or update then I will get a JSON response from the server -- some thing like this: 

"[{'error','CompanyId already in system'}]"

Any ideas on how I can use the datasource and/or grid to process this error response and allow the user to re-edit??

Thanks so much!!!
