[Solved] ASP.Net MVC Razor grid filtering

[Tatyana]

I am having a hard time figuring out how to extract a filtering expression from the grid to pass it to the service call where we do all the sorting and pagination. I found a way to get an expression by extracting the filterDescriptor string as:

[

 

GridAction(EnableCustomBinding=true)]

 

 

 

public ActionResult _CustomBinding(GridCommand command)

 

{

ViewData[

 

"total"] = 12;

 

ExpressionBuilder.Expression<Order>(command.FilterDescriptors).ToString();
//returns:
//"item => ((IIF((item != null), item.OrderID, null) ?? \"\").ToLower() == \"B100001\".ToLower())"

 

 

 

}

 

 

 

I am not sure how to parse or what to do with the returned string. Any ideas?

 

What is the right way to do it?
