[Solved] Auto-generate grid columns with collection of dynamic objects as model

[Monika]

My model is an IEnumerable which I would like to bind to a telerik mvc grid. Additionally the grid should auto-generate the columns and display everything from my dynamic object.

I found several posts on the telerik forum regarding this topic, like here: http://www.telerik.com/community/forums/aspnet-mvc/general/dynamically-generate-grid-columns.aspx

Unfortunately the result is the same: the grid displays the number of total rows in the footer but no rows are shown. I attached a sample project.

Any ideas?

Hello Monika,

I'm afraid that this is not supported because to the way reflection works on dynamic type. In the case in question, the IEnumerable<dynamic> is treated as IEnumerable<object> by the compiler, thus the inferred generic parameter of the Grid component will be object. This means that GetProperties on this type will yield no result. This can be tested by adding the following code to the View in the project you have sent us:

 

@model IEnumerable<dynamic>
@functions{
    int GetPropertiesCount<T>(T type)
    {
        return typeof(T).GetProperties(System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance).Length;
    }
}

@{
    var propertiesCount = GetPropertiesCount(Model.First());
}

Count @propertiesCount @*shows the properties count*@

As you can see this restriction comes from the framework, not from the product, so I am afraid we can't be of much help here.
