Dear Frnds,

I am developing Purchase order screen in mvc.. I have two models 'MRHdr' and 'MRDtl' How to use two models in single view. I am trying 3 days please help me...

Eg. Textbox values save in 'MRHdr' and grid values save in 'MRDtl'

What I have tried:

Models: public class MRHdr
{
[Key]
public int Id { get; set; }
public string MRNo { get; set; }
public DateTime MRDate { get; set; }
public string Remarks { get; set; }
}
public class MRDtl
{
[Key]
public int Id { get; set; }
public string MRNo { get; set; }
public string IRateCode { get; set; }
public string ItemCode { get; set; }
public int QtyRequested { get; set; }
}
View Model:
public class VwModel
{
public MRHdr MRHdr { get; set; }
public MRDtl MRDtl { get; set; }
}
Controller:
public ActionResult Create()
{
MRHdr objMRHdr = new MRHdr() { MRNo = "", MRDate = DateTime.Now };
MRDtl objMRDtl = new MRDtl() { IRateCode = "", ItemCode = "", QtyRequested = 0 };
List model = new List();
model.Add(new VwModel { MRHdr = objMRHdr, MRDtl = objMRDtl });

return View(model);
}

View:
@model Telecom.ViewModel.VwModel
@using (Html.BeginForm("Create", "MatReq", FormMethod.Post))
{

@{Html.RenderPartial("_MRHdrs",Model.MRHdr);}
@{Html.RenderPartial("_MRDtls", Model.MRDtl);}

}

Partial View:1
@model List< Telecom.Models.MRDtl >

Partial View:2
@model Telecom.Models.MRHdr

Use code block for your code...

By the way, it is very easy to find answer of such question using Google...

Solution 3

An article has already been written explaining many ways of accomplish this.

With a Google search of

mvc multiple models c#

, it was easy to find the information you need. You can try that yourself: Google[^]

Multiple Models in a View in ASP.NET MVC 4 / MVC 5[^]

That question also has already been asked on Stack Overflow:`
asp.net mvc - Multiple models in a view - Stack Overflow[^]

I would usually make another model that contains both models as properties and then create partial view for each part. This work well if each part are essentially independant (like combining 2 pages into one).

Same Error: u see above view, that given model is correct or not..

The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[Telecom.ViewModel.VwModel]', but this dictionary requires a model item of type 'Telecom.ViewModel.VwModel'.

Vivek.anand34 25-Jul-16 1:07am

public ActionResult Create()
{
MRHdr objMRHdr = new MRHdr() { MRNo = "", MRDate = DateTime.Now };
MRDtl objMRDtl = new MRDtl() { IRateCode = "", ItemCode = "", QtyRequested = 0 };
List model = new List();
model.Add(new VwModel { MRHdr = objMRHdr, MRDtl = objMRDtl });

return View(model);
}

Solution 2

Why not use two partial views and use one model for each.

I have updated my overall code above.. Error: The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[Telecom.ViewModel.VwModel]', but this dictionary requires a model item of type 'Telecom.ViewModel.VwModel'.

Solution 1

try like this

C#

public ActionResult Create()
       {
           MRHdr objMRHdr = new MRHdr() { /* initialise the properties*/ };
           MRDtl objMRDtl = new MRDtl() { /* initialise the properties*/  };
           VwModel model = new VwModel{ MRHdr = objMRHdr, MRDtl = objMRDtl };
           return View(model);
       }
       public ActionResult GetList()
       {
           MRHdr objMRHdr = new MRHdr() { /* initialise the properties*/ };
           MRDtl objMRDtl = new MRDtl() { /* initialise the properties*/  };
           List<VwModel> model = new List<VwModel>();
           model.Add( new VwModel{ MRHdr = objMRHdr, MRDtl = objMRDtl }); // sample
           model.Add(new VwModel { MRHdr = objMRHdr, MRDtl = objMRDtl }); // sample
           return View(model);
       }

Thanks.. But Error like this:
The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[Telecom.ViewModel.VwModel]', but this dictionary requires a model item of type 'Telecom.ViewModel.VwModel'.

Karthik_Mahalingam 23-Jul-16 2:37am

use @model Telecom.ViewModel.VwModel for getting only one item
and @model List< telecom.viewmodel.vwmodel > for list of model

Vivek.anand34 23-Jul-16 2:36am

How to initialize properties in object for eg.

Karthik_Mahalingam 23-Jul-16 2:38am

like this
{ new MRDtl { IRateCode="", ItemCode = "", QtyRequested=0 } };

Karthik_Mahalingam 23-Jul-16 3:04am

use this
@model Telecom.ViewModel.VwModel

Vivek.anand34 23-Jul-16 4:47am

s am using this only..

Vivek.anand34 25-Jul-16 1:06am

public ActionResult Create()
{
MRHdr objMRHdr = new MRHdr() { MRNo = "", MRDate = DateTime.Now };
MRDtl objMRDtl = new MRDtl() { IRateCode = "", ItemCode = "", QtyRequested = 0 };
List<vwmodel> model = new List<vwmodel>();
model.Add(new VwModel { MRHdr = objMRHdr, MRDtl = objMRDtl });

return View(model);
}

Karthik_Mahalingam 25-Jul-16 1:15am

this should work for
@model List< telecom.viewmodel.vwmodel >

Vivek.anand34 25-Jul-16 2:30am

I have updated overall code above..

Karthik_Mahalingam 25-Jul-16 2:40am

public class VwModel
{
public MRHdr MRHdr { get; set; }
public List< MRDtl> MRDtl { get; set; }
}

public ActionResult Create()
{
MRHdr objMRHdr = new MRHdr() { MRNo = "", MRDate = DateTime.Now };
MRDtl objMRDtl = new MRDtl() { IRateCode = "", ItemCode = "", QtyRequested = 0 };
List < mrdtl > lstDetails = new List < mrdtl > ();
lstDetails.Add(objMRDtl);
VwModel model = new VwModel() { MRHdr = objMRHdr, MRDtl = lstDetails };

return View(model);
}
