Appreciate your response, but I think I might not have been able to completely clarify what the problem is. As you know at the time of initializing the grid we specify the model type of the grid, so I set the model type as RoleRightsModel and set the grid as follows (Refer the model above in the question);

@(Html.Infragistics().Grid<RoleRightsModel>()
            .ID("RoleRightsGrid")
            .PrimaryKey("Module")
            .AutoGenerateColumns(false)
            .AutoGenerateLayouts(false)
            .RenderCheckboxes(true)
            .Height("500px")
            .Width("700px")            
            .Columns(column =>
            {
                column.For(x => x.Module).HeaderText("Module").DataType            ("string");        
            })               
            .ColumnLayouts(layouts =>
              {
                  layouts.For(x => x.ScreenType).                 
                  AutoGenerateColumns(false).                  
                  Columns(childcolumn =>
                  {
                      childcolumn.For(x => x.ScreenTypeName).HeaderText                            ("Screen Type").DataType("string");                                                
                  });                                    
              })
    //Till the end of the grid

This gives me something like;
 
 Module
+Module1
+Module2

On expanding any module i get;

 Module
-Module1
 ScreeType
  Reports
+Module2      

I want to go furthur down Reports and display all the screens asscoicated with it, in turn showing all the permissions given on that screen.

 Module
-Module1
 ScreeType
  -Reports
   -UserReport
    Add Edit Delete
   +FinancialReport
  +DI
  +RF
+Module2

The problem is that I cannot access the Screen and the Permission models in my grid, so that means I cant do something like;

.Columns(column =>
            {
                column.For(x => x.Module).HeaderText("Module").DataType            ("string");        
            })               
            .ColumnLayouts(layouts =>
              {
                  layouts.For(x => x.ScreenType).                 
                  AutoGenerateColumns(false).                  
                  Columns(childcolumn =>
                  {
                      childcolumn.For(x => x.ScreenTypeName).HeaderText                            ("Screen Type").DataType("string");                                                
                  });
              layouts.For(x => x.Screen).                 
                  AutoGenerateColumns(false).                  
                  Columns(childcolumn =>
                  {
                      childcolumn.For(x => x.ScreenName).HeaderText                            ("Screen Name").DataType("string");                          
                  });   
                  layouts.For(x => x.Permission).                 
                  AutoGenerateColumns(false).                  
                  Columns(childcolumn =>
                  {
                      childcolumn.For(x => x.CanAdd).HeaderText                                ("Screen Type").DataType("string");                                                
                  });                                    
              })

The data that gets passed to the view is something like this;

[{"Module":"Security Manager","ScreenType":[{"ScreenTypeName":"RF","Screen":[{"ScreenName":"Dashboard","Permission":[{"CanAdd":true,"CanEdit":true,"CanDelete":false,"CanPrint":false}]},{"ScreenName":"Home","Permission":[{"CanAdd":false,"CanEdit":false,"CanDelete":true,"CanPrint":false}]}]}]},

{"Module":"Sys Admin","ScreenType":[{"ScreenTypeName":"RF","Screen":[{"ScreenName":"Sys Admin Screen1","Permission":[{"CanAdd":false,"CanEdit":false,"CanDelete":true,"CanPrint":false}]},{"ScreenName":"Sys Admin Screen2","Permission":[{"CanAdd":false,"CanEdit":false,"CanDelete":true,"CanPrint":false}]}]}]}]

I would appreciate any help in this regards

Hello,

Thank you for the update. From what I can see from your model you would be able to display your Permission data as a child of the Screen so it would appear like the following:

1 RoleRightsModel  1(a) ScreenType   1(b) Screen    1(c) Permission

Currently the way you are setting your column layouts you have the ScreenType, Screen, and Permission all on the same level. If you want them to display on the same level you would have to modify the model to give the RoleRightsModel access to them directly. I recommend instead you setup the column layouts nested so that Screen appears under ScreenType and Permissions under Screen. In code this would look something like the following:

 
.Columns(column =>
             {
                 column.For(x => x.CategoryID).HeaderText("ID");
                 column.For(x => x.CategoryName).HeaderText("Name");
                 column.For(x => x.Description).HeaderText("Description");
             })
             .ColumnLayouts(layout =>
             {
                 layout.For(x => x.Products)
                     .ForeignKey("CategoryID")
                     .PrimaryKey("ProductID")
                    .AutoGenerateColumns(false)
                     .DataSourceUrl(Url.Action("BindProduct"))
                     .ColumnLayouts(lay =>
                         {
                             lay.For(z => z.ProdDesc)
                                 .ForeignKey("ProductID")
                                 .PrimaryKey("Number")
                                 .AutoGenerateColumns(false)
                                .DataSourceUrl(Url.Action("BindProdDesc"))
                                 .Columns(column =>
                                 {
                                     column.For(x => x.ProductID).HeaderText("ProductID");
                                     column.For(x => x.Number).HeaderText("Number");
                                     column.For(x => x.Desc).HeaderText("Desc");
                                 });
                         })
                     .Columns(column =>
                     {
                         column.For(x => x.ProductID).HeaderText("ID");
                         column.For(x => x.ProductName).HeaderText("Name");
                         column.For(x => x.CategoryID).HeaderText("Category");
                         column.For(x => x.UnitPrice).HeaderText("Unit Price");
                     });
             })
 

Hi,

I came across another issue, I want to enable editing in the lowest level of the model i.e the screen model and update it.

I specify the UpdateUrl at the end of the grid like this;

UpdateUrl(Url.Action("UpdateRoleRights")).AutoCommit(true)

Now when I modify the screen model (which is the lowest level of the model) and the update method is called I don't seem to get anything from the transactions;

List<Transaction<RoleRightsModel>> transactions = gridModel.LoadTransactions<RoleRightsModel>(HttpContext.Request.Form["ig_transactions"]);

But if I edit the top most level of the mode i.e the RoleRightsModel, I can get the transactions. How can I access the updated rows from the lowest level of the hierarchy? Thanks in advance.
