Data is visible in DataSet visualizer but does not show in a DataGrid

Question

my code is

public DataTable Load_to_DataGrid(string Line_ID)
{
    con.ConnectionString = ConfigurationManager.ConnectionStrings[1].ConnectionString;
    c         


        

Answer 1

When DataGrid generates columns for its ItemsSource, it uses DataTable column names as binding path for columns. While / symbol is valid in DataColumn names, in has a special meaning in binding path and should be escaped if it is a part of name, e.g. [80/4] not 80/4

add event handler to AutoGeneratingColumn event in xaml:

AutoGeneratingColumn="Dg_OnAutoGeneratingColumn"

and modify bindings with this code:

private void Dg_OnAutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
    var textCol = e.Column as DataGridTextColumn;
    if (textCol == null)
        return;
    var binding = textCol.Binding as Binding;
    if (binding == null)
        return;
    binding.Path = new PropertyPath("[" + binding.Path.Path + "]");
}
