I've a DevExpress XtraGrid control with three columns and a unbound checkBoxEdit column for users to select when deleting items from the grid. I'm able to add the checkBoxEdit on the xtraGrid. However, i don't have any idea as to how i can get the selected lists' primary key(s) to be deleted. Any idea is highly appreciated. Thanks
I believe you can use the following approach:
void InitGrid() {
gridControl1.DataSource = new List<Person> {
new Person(){ ID = 0 },
new Person(){ ID = 1 },
new Person(){ ID = 2 }
};
gridView.Columns["ID"].Visible = false;
gridView.Columns.Add(new DevExpress.XtraGrid.Columns.GridColumn()
{
UnboundType = DevExpress.Data.UnboundColumnType.Boolean,
Caption = "Mark as Deleted",
FieldName = "IsDeleted",
Visible = true,
});
}
IDictionary<int, object> selectedRows = new Dictionary<int, object>();
void gridView1_CustomUnboundColumnData(object sender, CustomColumnDataEventArgs e) {
int id = (int)gridView.GetListSourceRowCellValue(e.ListSourceRowIndex, gridView.Columns["ID"]);
if(e.IsGetData)
e.Value = selectedRows.ContainsKey(id);
else {
if(!(bool)e.Value)
selectedRows.Remove(id);
else selectedRows.Add(id, e.Row);
}
}
void OnDelete(object sender, System.EventArgs e) {
//... Here you can iterate thought selectedRows dictionary
}
//
class Person {
public int ID { get; set; }
public string Name { get; set; }
public string Age { get; set; }
}
