Trying to implement inline editing. Following is a simplified version.

EmployeeEditor.cshtml inside EditorTemplates folder

@(Html.Kendo().DropDownList()
                .Name("ToBranch") 
                .DataValueField("Id") 
                .DataTextField("Name") 
                .BindTo((System.Collections.IEnumerable)ViewData["toBranch"]) 
)

 

Employee class

public class Employee

{

  public string EmployeeName {get; set;}

  [UIHint("EmployeeEditor"]

  public string ToBranch {get; set;}

}

 

View

@Html.Kendo().Grid(Model.Employees)
            .Name("BranchGrid")
            .Columns(col =>
            {
                col.Bound(o => o.EmployeeName);
                col.Bound(o => o.ToBranch);
                col.Command(command => { command.Edit(); });
            })
            .Editable(editable => editable.Mode(GridEditMode.InLine))
            .DataSource(dataSource => dataSource
            .Ajax()
            .Model(model =>
            {
                model.Field(o => o.EmployeeName).Editable(false);
            })
            .Update(update => update.Action("EditingInline_Update", "BranchForm"))
            .ServerOperation(false))
            .Events(events => events.DataBound("error_handler"))
            .Render();

 

Controller

public ActionResult Index()

{

   //Populate a model

   ViewData["toBranch"] = branches 

   return View(model);

}

/////// Important Part

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult EditingInline_Update([DataSourceRequest] DataSourceRequest request, Employee model)
{

//// If there was a branch initially say 24 and I change it to 28, I do see model.ToBranch as 28  ( works fine)

//// However, if the branch was initially an empty string and I change it to 28, model.ToBranch is "[Object object]"

}

 

Can you please tell me why this is happening? This is kind of critical and an urgent reply would be really appreciated

Hello,

The issue is caused since the ToBranch field is of type string but its drop down editor is an object with Id and Name fields. What happens is when the user selects a value from the drop down an object is passed to the string field which is stringified and ends up as [Object object].

To avoid the issue I would suggest you to simply bind the drop down to a collection of strings (I assume Name values from current objects) and remove the DataValueField and DataTextField configuration.
