Checking condition inside client template in Telerik Grid ASP.NET MVC Razor.

Hi,

I want to check some condition inside the client template. I am displaying certain model properties in ordered list some properties might be null. 

I want to check if it is empty i should not display the template.

colums.Bound(o => o.Order1).ClientTemplate( "

1. <#= Order1 #>
" + "
2. <#= Order2 #>
" + "
3. <#= Order3 #>

" ); 

Here is a sample of a client template which is using conditions:

ClientTemplate("<# if (OrderID > 10)  { #> <#= OrderID #> <# } else { #> <#= OrderID #> <# } #>");

<# is the client-side equivalent equivalent of <% where <#= is the client-side equivalent of <%=.

Ado.net - the Size property has an invalid size of 0

I'm trying to get output value from DB via ADO.net. There's a client code:

    using (var connection = new SqlConnection(ConnectionString))
    {
        connection.Open();
        SqlCommand command = new SqlCommand("pDoSomethingParamsRes", connection);
        command.CommandType = CommandType.StoredProcedure;
        command.Parameters.Add("@i", 1);
        var outParam = new SqlParameter("@out", SqlDbType.VarChar);
        outParam.Direction = ParameterDirection.Output;
        command.Parameters.Add(outParam);
        command.ExecuteNonQuery();
        Console.WriteLine(command.Parameters["@out"].Value.ToString());
    }

When I run this I get the following exception:

the Size property has an invalid size of 0

Solutions :-

VarChar and NVarChar are variable width character fields (thus var+char). You have to set the length, otherwise the default is zero.

outParam.Size= int.MaxValue

to define maximum value of integer.
