[Solved] Query string issue

[Slava Fedorchuk]

Basically - when query string is not well-formatted this causes an exception on a page with the Grid:
http://localhost:9500/Index?Grid-page=1&

    Exception Details: System.ArgumentNullException: Value cannot be null.
    Parameter name: key

Line 69: Html.Telerik().Grid(Model.results)

Here is a "working" example:

Another one:

Hi Slava Fedorchuk,

Thank you for reporting this problem. To fix it open the GridUrlBuilder.cs file and locate the PrepareRouteValues method. Now change this code:

if (!result.ContainsKey(key))
{
 result[key] = grid.ViewContext.HttpContext.Request.QueryString[key];
}

to this

if (key != null  && !result.ContainsKey(key))
{
   result[key] = grid.ViewContext.HttpContext.Request.QueryString[key];
}

All the best,
