I downloaded Ian Griffiths bindable listview code and successfully bound an XML file to it. I am having problems when trying to add a new row of information however. The row adds to the dataset and even saves to the XML file properly but it keeps displaying the item twice in the listview. Below is the code I use to add the new row:

PC_Milestone_Form pcmf = new PC_Milestone_Form();
DialogResult res = pcmf.ShowDialog();
if (res == DialogResult.OK)
{
    //add new milestone
    ProjectCommander.MilestoneItemRow row = projectCommander.MilestoneItem.NewRow() as ProjectCommander.MilestoneItemRow;
    row["Date"] = pcmf.textBox_Date.Text;
    row["Event"] = pcmf.textBox_Milestone.Text;
    row["project_ID"] = _projectID;
    projectCommander.MilestoneItem.AddMilestoneItemRow(row);           }


The question is am I adding the row incorrectly or is the bindable listview code I downloaded doing something wrong?

Further to this, when I delete an entry the next row in the listview disappears as well. However it isn't deleted from the XML file.

Is the code I show above the proper way to add a row of data to bound compenents?

I have the deletion problem also. I have a BindingList for a data source, which I provide to the BindableListView. When I remove an item from the BindingList, the ListViewItem in the BindableListView associated with that item disappears, and so does the one for the next item.

When I call BindingList.Remove() to remove the desired item, I observe that:

* BindableListView.currencyManager_ItemChanged() is called, where the given ItemChangedEventArgs.Index is -1.

* That causes BindableListView.LoadItemsFromSource() to be called, which repopulates the ListViewItems.

* Then, BindableListView.bindingList_ListChanged() is called, where the given ListChangedEventArgs.ListChangedType is ItemDeleted. This causes another ListViewItem to be erroneously removed.

I experience this problem even when I encase my item removal in BeginUpdate...EndUpdate calls as Paul Hildebrandt suggested in his solution.

(For my own reference, this is a comment to a question titled "bindable listview seems to duplicate entries".)

Got the solution. I had to encase the above code with:

listview.BeginUpdate();

if condition code above here

projectCommander.AcceptChanges();
listview.EndUpdate();
