[Solved] Drop Down List In Grid (Edit Issues)

[lmf232s]

Having issues getting a pretty basic drop down to work with a grid.

I have a Batch Object that has a CompanyId. In the grid I want to Display the company name associated with the Batch and be able to updated this with a drop down.

Now with jumping though many hoops (Attributes, KnownTypes, ViewModels, Display & Edit Temmplates) I have seemed to get this to work with one exception. After my update the Company field now displays [object object].

I have looked through the documentation and searched the forms but have not come across anything that has helped. The documentation only shows an example of string dropdown, no one that stores the ID. There is an example of the complex type which is what im attempting but again I all ways end up with [object object] after the grid updates.

The company names does display correctly on page load.

Any ideas, suggestions?

Hi lmf232s,

 This can appear if you are trying to edit or bound a complex object. The grid currently displays [object object] as this is what the toString() JavaScript method returns. Perhaps this is the problem. You can try using a client template to display a meaningful property of your object.

All the best,

i have run into the same problem
and tried to use Client Template but the column is showing empty data.

columns.Bound(m => m.Worker).ClientTemplate("<#=Worker.Name#");

any ideas ?

Nour,

was finally able to get this working. I just had to restart from the beginning with a very basic example and work up to what I needed. What you need to do is create a Display Template for your object Worker. Its really just as easy as this: (This assumes you have a Name property on worker but you get the idea)

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Worker>" %>
<%: Model.Name%>

One last thing, you'll need to decorate your model with a UIHInt attribute. This needs to go on your model that has the FK reference to the Worker Object. It would look something like this :

public partial class SomeObject{
    [UIHint("Worker"), Core.Validation.Required]  
    public virtual int WorkerId { get; set; }
}

Hope that helps

thank you lmf232s, but that exactly what i did, the problem doesn't lie in filing the grid for the first time with some data, but the problem shows up when you edit a row or insert a new one, when using Ajax binding.
what i think is that json object which came from the controller, is not well defined !!!!!

and here is my question more specific:
Editing Telerik row whith ajax

Atana,
what do you suggest?
could i use some java script in the Client template ??
and if so, how can i do it ?

Run in to same issue.
on Edit event I got  null object for

$(e.form).find('#name).data('tDropDownList')

 

• 'tDropDownList' is null.
• Display template is fine. It fills up data when render.
  
  Any suggetion?
