MVC partial view wtih different model - asp.net-mvc-4

Question

I have model as
public class MainDataViewModel
{
[Required]
[Display(Name = "Select Work Orders")]
public string[] SelectedWorkOrdersValues { get; set; }
public MultiSelectList WorkOrderIds { get; set; }
public IEnumerable<ORDERMASTER> ordersDetails;
}
And Main View as
#model InventoryEasy15.Models.MainDataViewModel
<div class="box-body">
<div class="col-md-6">
<div class="form-group">
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<label for="fileToUpload">Select the Work Orders</label>
#Html.ValidationMessageFor(m => m.WorkOrderIds, "", new { #class = "text-danger" })
#Html.ListBoxFor(m => m.SelectedWorkOrdersValues, Model.WorkOrderIds as MultiSelectList, new { id = "WorkOrders", #class = "form-control", data_placeholder = "Choose Work Orders..." })
</div>
</div>
</div>
<!-- /.box-body -->
<div class="box-footer">
<input type="submit" value="Get WorkOrder Details" id="btnSubmit" class="btn btn-primary">
</div>
</div>
</div>
</div>
#Html.Partial("MainDataWorkOrderDetails", Model.ordersDetails)
And the Partial view as
#model IEnumerable<InventoryEasy15.ORDERMASTER>
<div id="myDisplayID"><div>
Now I am getting error as
The model item passed into the dictionary is of type 'InventoryEasy15.Models.MainDataViewModel', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[InventoryEasy15.ORDERMASTER]'.
Any thoughts.
The controller here is
public async Task<ActionResult> MainDataWorkOrderDetails(MainDataViewModel m)
{
var model = new MainDataViewModel();
var result = await db.ORDERMASTERs.Where(x => x.WOID == "WO7446708").ToListAsync();
if (result != null)
{
model.ordersDetails = result;
}
return PartialView(model);
}

Answer 1

You are passing model to the PartialView. Now, the model is of type MainDataViewModel, and your partial view expects the model of type IEnumerable<InventoryEasy15.ORDERMASTER>
return PartialView(model);
I think you should consider passing model.orderDetails to the partial view from your action.
return PartialView(model.orderDetails);
Or else, simply return the View containing the partial view if you want to pass the whole model
