Populate Listview from Datatable
Posted on 2010-09-05
I am trying to populate a listview from a stored procedure, I can verify all data are being returned just fine but not populated properly in the listview.
I am trying to display 3 columns in my listview, but instead only the first column is showing.
here is my code:
Those are the only records in my table and the represent the ItemNo.
1- Anyone knows what wrong with the code above and not the Name and Qty fields are not showing the listview?
2- How can get rid of the ( ListViewItem: ) caption/header showing in the listview above?
Thanks

DataTable dt = ds.Tables[0];
// Clear the listview control
lstItems.Items.Clear();
lstItems.MultiColumn = true;
lstItems.BeginUpdate();
// Display items in the ListView control
for (int i = 0; i < dt.Rows.Count; i++)
{
DataRow dr = dt.Rows[i];
// Only row that have not been deleted
if (dr.RowState != DataRowState.Deleted)
{
// Define the list items
ListViewItem lvi = new ListViewItem(dr["ItemNo"].ToString()); //SHOWS
lvi.SubItems.Add(dr["Name"].ToString()); //DOES NOT SHOW
lvi.SubItems.Add(dr["Qty"].ToString()); //DOES NOT SHOW
// Add the list items to the ListView
lstItems.Items.Add(lvi);
}
}
lstItems.EndUpdate();
What the code above shows when running it is the following:
ListViewItem: {12345}
ListViewItem: {56789}
ListViewItem: {12}

I already tried to bind its datasource = dt but it didn't work as the result showing are
System.Data.DataRowView
Instead of actual values.
I am interested in knowing why my code above doesn't show all columns and only shows one column (one value). All values (rows) are showing properly in the datarow

Hi smaguire;
In order to display columns you need to set the ListView to Detail view, so try making the following change:
// Clear the listview control
lstItems.Items.Clear();
lstItems.MultiColumn = true;
// Set to details view.
lstItems.View = View.Details;
I think that should get it to work for you.

Fernando,
I don't have the .View option! I am using ListView version 4.0.0.0 but no .View property is available to me.

Fernando,
I was able to get the .View property to display, I had to remove and then add the reference pointing to it and the property showed just fine, however now it doesn't display anything.
The list is not populated. any thoughts? Is there a better way populating a listview from a stored procedure?
Thanks

Hi smaguire;
Sorry I left home after posting my last post and forgot to also include adding column headers which is also needed when using Detail view. In the below statements the second parameter is the initial column width, you can leave it out be the default is always not wide enough. You can set it to the widest you think you need.
// Clear the listview control
lstItems.Items.Clear();
// Set to Datail View
lstItems.View = View.Details;
// Define the columns
lstItems.Columns.Add("Item
lstItems.Columns.Add("Name
lstItems.Columns.Add("Qty"
