[Solved] Problem while sorting in the Grid.

[Sasikanth KS]

Hi,

While sorting an property at second level of the object then I am getting error "Invalid property or field", Please check the below code as well attached screenshot, in the below code "Fund Type" and "Ticker" is working as expected but "Fund Name" is getting error while sorting, "Fund Type" and "Ticker" is at first level but "Fund Name" is at second level. Is any thing I am missing, please suggest.

    investmentPerformance.Add(properties => properties.InvestmentInformation.InvestmentType)

                                        .Title(

"Fund Type");

 

    investmentPerformance.Add(properties => properties.InvestmentInformation.Investment.InvestmentLongName)

                                        .Title(

"Fund Name");

 

    investmentPerformance.Add(properties => properties.InvestmentInformation.Ticker)

                                        .Title(

"Ticker");

 

Thanks

Hello Sasikanth KS,

It seems you have discovered a bug in our code. Fortunately it is rather easy to fix. Please open the ExpressionExtensions.cs file (from the Telerik Extensions source) and replace the MemberWithoutInstance method implementation with this code:

public static string MemberWithoutInstance<T>(this Expression<Func<T, object>> expression) where T : class
        {
            MemberExpression memberExpression = expression.ToMemberExpression();

            if (memberExpression == null)
            {
                return null;
            }

            if (memberExpression.Expression.NodeType == ExpressionType.MemberAccess)
            {
                MemberExpression innerMemberExpression = (MemberExpression)memberExpression.Expression;
                
                while (innerMemberExpression.Expression.NodeType == ExpressionType.MemberAccess)
                {
                    innerMemberExpression = (MemberExpression)innerMemberExpression.Expression;
                }

                ParameterExpression parameterExpression = (ParameterExpression)innerMemberExpression.Expression;

                return memberExpression.ToString().Substring(parameterExpression.Name.ToString().Length + 1);
            }

            return memberExpression.Member.Name;
        }

Then rebuild the solution and use the produced assembly. We will release a hotfix build soon.
