DataTable Column Header containing "," symbol prevents cell rendering in WPF DataGrid

[SreemonPremkumarM]

Description

When binding a System.Data.DataTable to a WPF DataGrid, if the DataColumn.ColumnName contains a "," (Comma), all subsequent cells in that column fail to display values.

In the output, it throws the binding error as ,

System.Windows.Data Error: 40 : BindingExpression path error: '[]' property not found on 'object' ''DataRowView' (HashCode=20668333)'. BindingExpression:Path=[a,b_0]; DataItem='DataRowView' (HashCode=20668333); target element is 'TextBlock' (Name=''); target property is 'Text' (type 'String')

Datatable codes:

 DataTable dataTable = new DataTable();
 dataTable.Columns.Add("a,b", typeof(int));
 dataTable.Columns.Add("cb", typeof(string));
 dataTable.Columns.Add("Customer ID", typeof(string));
 dataTable.Columns.Add("Country", typeof(string));

 dataTable.Rows.Add(1001, "Maria Anders", "ALFKI", "Germany");
 dataTable.Rows.Add(1002, "Ana Trujilo", "ANATR", "Mexico");
 dataTable.Rows.Add(1003, "Antonio Moreno", "ENDGY", "Mexico");

Column Declaration:

 private void FradataGrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
 {
     e.Column = new DataGridTextColumn { Header = e.Column.Header, Binding = new Binding("[" + e.Column.Header + "]") };
 }

Sample Attached: DataGrid_WPF.zip

Reproduction Steps

1. Run the attached sample.
2. Observe the column "a,b0".
3. Check the output for the binding error.

Hi,

The Characters like "." and "/" are working as expected. The values are displayed correctly in the column, and no binding errors are observed. However, using comma "," appears to cause issue. I have attached the image reference below.

DataGrid with column name using ".":

DataTable dataTable = new DataTable();
dataTable.Columns.Add("a.b", typeof(int));

DataGrid with column name using "/":

DataTable dataTable = new DataTable();
dataTable.Columns.Add("a/b", typeof(int));

Column Declaration:

private void FradataGrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
    e.Column = new DataGridTextColumn { Header = e.Column.Header, Binding = new Binding("[" + e.Column.Header + "]") };
}
