Parameter nulll

[Alberto]

I'm tying to use thi s parameter "NumberGroupSizes="3" to specify the size of group in order to separate correctly a number.

But i have the esception of paramter null.

So how can i write 1.000,45 fo example?

Hi  Alberto,   

    

Thanks for contacting Syncfusion support. 

 

We have checked your query for “Parameter null exception while setting NumberGroupSizes”. The NumberGroupSizes in the GridNumericColumn is the int array property so we need to set the int array for NumberGroupSizes.  Please refer the below example to set the NumberGroupSizes property. 

 

If you define the columns in XAML you can use the below example. 

 

//ViewModel 

public int[] a { get; set; }  

public ViewModel() 

{ 

  a = new int[3] { 2, 3, 1 }; 

} 

 

 <sfgrid:GridNumericColumn HeaderText="Order ID"  

                           NumberDecimalDigits="0"  

                           NumberGroupSizes="{Binding a,    

                                Source={x:Reference viewModel}}"  

                           MappingName="EmployeeID"  /> 

 

If you define the columns in code behind you can use the below example. 

  

public partial class MainPage : ContentPage 

{ 

        public MainPage() 

    { 

            InitializeComponent(); 

            int[] a = new int[3] { 2, 3, 1 }; 

 

            GridNumericColumn customerColumn = new GridNumericColumn(); 

            customerColumn.MappingName = "EmployeeID"; 

            customerColumn.HeaderText = "Salary"; 

            customerColumn.NumberGroupSizes = a; 

            customerColumn.NumberDecimalDigits = 0; 

  } 

} 

 

We have prepared a sample for your requirement and you can download the same for the below link.
