Dynamic Model

Hi guys,
i'm trying to implement the Syncfusion MVC Grid an i have a problem with my dinamical model in the view.

In my product i have a model which returns a List of dynamical objects (i get the date from a thirth party, so i can't chage it and i won't to wrap it). Here the simple example:

public class Foo
{
public List getBoo()
{
List list = new List();
dynamic obj;

for (int i = 0; i < 15; i++)
{
obj = new System.Dynamic.ExpandoObject();
obj.aaa = "aaa";
obj.bbb = "bbb";
obj.ccc = "ccc";
obj.ddd = "ddd";
obj.eee = "eee";
list.Add(obj);
}
return list;
}
}

And here is the controller:

public ActionResult Grid()
{
Foo mod = new Foo();
var myMod = mod.getBoo();

GridPropertiesModel model = new GridPropertiesModel()
{
DataSource = myMod,
AllowPaging = true,
AllowSorting = true,
Caption = "All Bla's",
AutoFormat = Skins.Midnight,
AllowFiltering = true,
AllowGrouping = true,
Localize = System.Threading.Thread.CurrentThread.CurrentUICulture.Name,
LocalizationPath = "~/App_GlobalResources"
};

ViewData["GridModel"] = model;
return View();
}

So my question is, how looks the view? Any ideas?
I try with:
@{

Html.Syncfusion().Grid("myDinamicalGrid", "GridModel",
column =>
{
column.Add(p => p.aaa).HeaderText("This is aaa");
column.Add(p => p.aaa).HeaderText("This is aaa");

});
}

Hi Petar Raykov,

Thanks for using Syncfusion Products.

Currently we do not provide 'support to binding dynamic objects'. This has been confirmed as a Feature Request.

We will implement this feature in our forthcoming new version releases or service pack releases.
We usually have an interval of at least three months between releases. The feature implementation
would also greatly depend on the factors such as product design, code compatibility and complexity.
We will get back to you once the feature is implemented.

Please let us know if you have any concerns.

Regards,
Bala Murugan A.S

Hi Bala Murugan,

thank you for your post.
Is there any workarounds, that can i use?
I get the Model on runtime, so i can't create a model on the desing time.

Kind regards,
Petar Raykov


PR Petar Raykov March 27, 2012 07:14 AM UTC

Hi me again,

i have another idea but it doesn’t work too. I would like to have a model with only one property e.g. Values from Type String Array. For instance:

namespace MyNamespace.Models
{
public class TestObject
{
public string[] Values { get; set; }
}
}


The idea is to use a for-loop over the property inside the view. For instance:

@(new HtmlString(Html.Grid("Grid1","GridModel", columns =>
{
for(int i = 0; i < p.Values.Count; i++)
{
columns.Add(p => p.Values[i]);
}
}).ToString()

Is there any workaround?

Kind regards,
Petar Raykov

Hi Petar Raykov,

Thanks for your patience,

We are tried on your requirement but there is no workaround available on binding object dynamically. We have prepared simple sample of binding objects to grid with a help of ITypedList and same can be downloaded from the below link.

Sample link: http://www.syncfusion.com/downloads/Support/DirectTrac/91680/DynamicModel-352789180.zip

Could you please have a look at the above sample and let us know if this sample meets your requirement of binding object to grid?

Please let us know if you have any concerns.

Hi Bala,

unfortunately this isn't my intention.

I'm implementing a client of a server-client system. The data for the grid comes from the server component via WCF.
I get a table structure as Datatable() with header label and strongly typed values:

ID (int) | Name (string)| Property (int) | Date (date)
1 | lorem | 12 | 12.05.2012
2 | ipsum | 10 | 10.05.2012
3 | dolor | 24 | 14.05.2012

The big problem is, that I don't know the structure (heder names and types) on the DESIGN time, it depends on the server settings.

My intension was to use an ExpandoObject with dynamical properties so I can add them on the run time. As far as I understood the Syncfusion MVC Grid doesn’t support this .NET feature.
So my idea is to use an array, hashtable or datatable as a datacontainer.

The disadvantage of your example is, that the properties of Customer class you are using in your example are known on the design time and this is what I don’t know on the design time.

Kind regards,
Petar Raykov

Hi Petar Raykov, I have the same problem with dynamic models. 
Did You solve the problem? 

I bind datatable to a sync grid, the columns names and count rows are good, but the row contents is not showing. 

Any idea?

Thanks for the reply. 
Now I need to edit the datatable in the grid, but I have problems with DataRow Id, when I click in delete or add or edit, in de server method I'dont see de parameters or de editing row content

This is my code: My Id is "ObjectId"

DataTable:

public EnumerableRowCollection<DataRow> GetDataTable()
        {
            //
            // Here we create a DataTable with four columns.
            //
            DataTable table = new DataTable();
            table.Columns.Add("ObjectId", typeof(string));
            table.Columns.Add("Dosage", typeof(string));
            table.Columns.Add("Drug", typeof(string));
            table.Columns.Add("Patient", typeof(string));
            table.Columns.Add("Date", typeof(string));

            DataColumn[] key = new DataColumn[1];
            key[0] = table.Columns["ObjectId"];
            table.PrimaryKey = key;
            
            // Here we add five DataRows.
            //
            table.Rows.Add("1", 25, "Indocin", "David", DateTime.Now.ToShortDateString());
            table.Rows.Add("2", 50, "Enebrel", "Sam", DateTime.Now.ToShortDateString());
            table.Rows.Add("3", 10, "Hydralazine", "Christoff", DateTime.Now.ToShortDateString());
            table.Rows.Add("4", 21, "Combivent", "Janet", DateTime.Now.ToShortDateString());
            table.Rows.Add("5", 100, "Dilantin", "Melanie", DateTime.Now.ToShortDateString());
 
            return table.AsEnumerable();
        }

View:
<div style="width:100%;">
    @(Html.Syncfusion().Grid<DataRow>("JSONCRUD")
                        .Datasource((IEnumerable<DataRow>)ViewData["data"])
                        .AutoFormat(Skins.Marble)
                        .EnablePaging()
                        .EnableSorting()
                        .ActionMode(ActionMode.JSON)
                        .Caption(ViewData["RelationTitle"].ToString())
                        .ToolBar(tools => tools.Add(GridToolBarItems.AddNew)
                                              .Add(GridToolBarItems.Edit)
                                              .Add(GridToolBarItems.Delete)
                                              .Add(GridToolBarItems.Update)
                                              .Add(GridToolBarItems.Cancel))
                                             .Mappers(mapper => mapper.InsertAction("AddItem")
                                                                    .SaveAction("SaveItem")
                                                                    .DeleteAction("DeleteItem"))
                                            .Editing(edit =>
                                            {
                                                edit.AllowEdit(true)
                                                    .AllowNew(true)
                                                    .AllowDelete(true);
                                                edit.EditMode(GridEditMode.Normal);
                                                edit.PrimaryKey(key => key.Add(p => p.Table.PrimaryKey));
                                                
                                            }))
</div>

And my controller

   [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult EditableRelationGrid(PagingParams args)
        {
            IEnumerable data = GetDataTable();
            return data.GridJSONActions<DataRow>();
        }

        [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult SaveItem(DataRow row)
        {
            _moreObjectManager.Update(row);
            var data = GetDataTable();
            return data.GridJSONActions<DataRow>();
        }

        [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult AddItem(DataRow row)
        {
           _moreObjectManager.Add(row);
            var data = GetDataTable();
            return data.GridJSONActions<DataRow>();
        }

        [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult DeleteItem(string rowId)
        {
           _moreObjectManager.Delete(rowId);
            var data = GetDataTable();

Hi German,

 

Thanks for using Syncfusion Products.

 

Query 1: To edit the datatable in the grid.

 

We have noticed that you have used “ edit.PrimaryKey(key => key.Add(p => p.Table.PrimaryKey)); “ in your view page to specify the Primary Key property for grid. We suggest you to use the below code snippet for setting primary key.

 

[view]

.Editing(edit =>{

                     edit.PrimaryKey(new string[]{"ObjectId"});

})

 

For your convenience we have your modified your codes and created a sample for performing editing, deleting, adding operations in grid using datatable binding. Please try the below sample and let us know if you have any concerns.

Rakesh D

GE German October 23, 2012 06:44 PM UTC

HI, thanks for reply and sample, but you don't understood what is an "dynamic model".

The functions in your sample isn't dynamic, because columns are fixed in save,edit, methods. 
In the same page and grid I need to bind datatables with different count of columns, all of this, generated by code in runtime, so, I don't know de name of de columns or de count of this at design time: 
    
Your example works fine, but It isn't dynamic datatable, and It isn't dynamic count of columns.

 Now, when I used a datable to bind a grid, I see "column name" property of "datacolumn" in header text, and not column caption. Is it supporting in the Syncfusion grid?

[view]

.Editing(edit =>{

                  edit.PrimaryKey(new string[]{"ObjectId"});

Query 2: To set Column caption or HeaderText.

To set column caption or HeaderText we suggest you to use HeaderText property of column. Please refer below code snippet for further details.

.Column(col =>{col.Add("ObjectId").HeaderText("OBJECT ID");})

For your convenience we have your modified your codes and created a sample for performing editing, deleting, adding operations in grid using datatable binding. Please try the below sample and let us know if you have any concerns.

Hello ,

I want to achieve following dynamically without specify model Name for List in Batch Update .

So give me Idea to achieve result without specify model Name
