[Solved] How to get the value of a cell when the columns are dynamically generated?

[Paul Hoeffer]

I'm trying to understand how to get the contents of a cell in grid where the columns are dynamically generated.

For instance, if I want to change the style of a cell to reflect that of it's contents like:

.CellAction(cell => {

    cell.HtmlAttributes[

 

"style"] = "cls-rankings-" + cell.Text;

 

})

the contents of cell.text are always empty.  Since the columns come from a DataTable I can't hard code them, e.g. cell.DataItem.SomeColumnName

Is there anyway to do this? It seems like it should be trivial - what am I missing?

Hi Paul,

 As you are using DataTable for a grid's data source you can very easily get a given data item's field value by current column's member name.

<%=Html.Telerik().Grid(Model).Name("Grid")// Note: the Model is of type DataTable
     .CellAction(cell => cell.HtmlAttributes["class"] = "cls-rankings-" + cell.DataItem[cell.Column.Member])
%>

All the best,

Perfect!!

Quick question, what if the Model is a custom type, e.g. class Foo with 5 properties.  Is there any way to access that generically as well w/o having to specify the property name?

Hi Paul,

You may consider using reflection or construct a lambda expression tree to extract the value.
