DataSet created in code not Binding to ListView - wpf

Question

I have a WPF User Control with a ListView in it that is created based on the DataSet that is passed to it:
public void PopulateList(DataSet ds) {
listView.View = CreateGridViewColumns(ds.Tables[0]);
listData.DataContext = ds.Tables[0];
}
private GridView CreateGridViewColumns(DataTable dt) {
// Create the GridView
var gv = new GridView {AllowsColumnReorder = true};
// Create the GridView Columns
foreach (DataColumn item in dt.Columns) {
var gvc = new GridViewColumn
{
DisplayMemberBinding = new Binding(item.ColumnName),
Header = item.ColumnName,
Width = Double.NaN
};
gv.Columns.Add(gvc);
}
return gv;
}
Now I create the user control in code and call it's PopulateList with the appropriate dataset and this is where the problems are starting:
If I pass in a dataset that was created from a call to the database the list view shows all the data but if i pass in a DataSet that i created in code the ListView shows the Columns but will not show the data
//This is a function that hides the DB call return type is DataSet
var dsPatientSmokingStatusHistory = DataRepository.PatientSmokingStatusProvider.GetHistory(PatientId);
//radGridViewPatientSmokingStatus.DataSource = dsPatientSmokingStatusHistory.Tables[0];
var dt = new DataTable();
string c1 = "Date".PadLeft(23).PadRight(23);
string c2 = "Status".PadLeft(20).PadRight(50);
dt.Columns.Add(c1);
dt.Columns.Add(c2);
int i = 0;
foreach (DataRow row in dsPatientSmokingStatusHistory.Tables[0].Rows) {
var dataRow = dt.NewRow();
dataRow[c1] = ((DateTime)row["Date"]).ToString("MM/dd/yyyy");
dataRow[c2] = row["Status"].ToString();
dt.Rows.Add(dataRow);
dt.Rows[i].AcceptChanges();
i++;
}
DataSet ds = new DataSet();
dt.TableName = "Table";
ds.Tables.Add(dt);
ds.AcceptChanges();
smokingStatusGrid.GridWidth = 455;
smokingStatusGrid.GridHight = 97;
//This line does not show data
smokingStatusGrid.PopulateGrid(ds);
//This line will show data
smokingStatusGrid.PopulateGrid(dsPatientSmokingStatusHistory);
Is there a difference between these two datasets that i don't know about that is preventing me from databinding to it?
Also the user control is being used as an ElementHost in a WinForms application (not sure if this makes a difference)

Answer 1

Your code says:
DisplayMemberBinding = new Binding(item.ColumnName)
This binding constructor takes a string paramter which as per MSDN is "The initial Path for the binding" and is of datatype System.Windows.PropertyPath. I guess, since system tries to find a property with the same name in your class, and your string (item.ColumnName) has spaces at start, it runs into a problem (properties can't start with a space).
Would recommend you to take off the padding that you are doing in column name of your table. Apply any padding/margins in the Header of your GridView.
