I have worked based on : .Filter(filter => filter.Add(/* your filter rule */)) , that I found in here.

 My code is : 

  var grid =
        Html.Kendo().Grid<dynamic>().Name(Model.Current.Id).HtmlAttributes(new
        {

           // lot of stuff

       }

 grid.DataSource(ds =>
    {
        var ajaxDsBuilder = ds.Ajax();
        ajaxDsBuilder.Model(model => model.Id("ID")).Events(ev => ev.Error("gridOnError")).ServerOperation(Model.Current.LazyLoading);

// mode code

      var cols = Model.Current.Columns.ToList();

           foreach (var col in cols)
              {​

                 ajaxDsBuilder.Sort(sort => sort.Add(col.Name).Ascending()); // this works perfect for pre-sorting     ( col.Name = the column name ) 

                 ajaxDsBuilder.Group(grp => grp.Add(col.Name, typeof(string))); // this the same works great for pre-grouping

 ​but when I try this:

          ajaxDsBuilder.Filter(f => f.Add(c=> c.col.Name).IsEqualTo("TEST")); ​

I get : Error309 An expression tree may not contain a dynamic operation 

if I try:  ajaxDsBuilder.Filter(f => f.Add(c=> col.Name.ToString()).IsEqualTo("TEST")); ​// I am overriding ToString() to give me the name of column

I get : Internal server error

 if I try:  ajaxDsBuilder.Filter(f => f.Add(c=> col.Name).IsEqualTo("TEST")); 
I get : Property with specified name: col.Name cannot be found on type: System.Data.DataRowView

I have also worked with lambda expressions, but I have pretty much the same errors. 

My grid has to be dynamic, so I can't change that.

Any help?

 Asp.net MVC 5

I need to pass a value to to the grid so it is populated automatically (see attached screenshot).  I have google'd looked at these forums, but the following doesn't seem to populate the value in the grid.

I know how to do this with through an Actionlink:

Please advise.

Hello

I have a grid displaying workitems and the last action taken for a workitem, recently I discovered that I need to extend this to include a history of actions stored in a separate table in the db.

the two tables looks like this:

workItem
id
name
lastActionDate
lastActionText

workAction
id
workItemID
actionDate
ActionText

My model currently looks like this:

and my read action for the grid looks like this:

How do I extent my model and my read action to include the workAction table from the db?

Dear Telerik Community,

 I've recognized some weird behavior of the DatePickerWidget when switching from one month to another. You can take a look at the screen shot to see exactly what I'm talking about. I don't know if this already came up to somebody of you - I hope it did so someone can help me fix it.

 Kind regards,

Thomas
