Datagridview System.indexoutofrangeexception Index 0 Does Not Have A Value
a value up vote 1 down vote favorite 1 I am getting one error when I am trying to populate binding source. The exception is as follows; System.IndexOutOfRangeException: Index 0 does not have a value. at System.Windows.Forms.CurrencyManager.get_Item(Int32 index) at System.Windows.Forms.DataGridView.DataGridViewDataConnection.GetError(Int32 rowIndex) I am using generic list to fill binding source. The code looks like, foreach (listItem) { BindingSource.Add(listItem); } I tried resetting the datasource property, but still the datagridview index does not have a value same issue. Please help me to resolve this issue. Thanks in advance. c# datagridview bindingsource indexoutofboundsexception share|improve this question asked Oct 12 '11 at 8:41 Vijay Balkawade 1,72893369 add a comment| 3 Answers 3 active oldest votes up vote 3 down vote As far as I understand, you don't have to populate BindingSource, you just have to populate the list it's bound to. That's the whole idea of binding. You bind your control to the data using bindingsource. And then myBindingSource.DataSource = listItem; will do it. Also, instead of binding your datagridview to BindingSource and your BindingSource to list, you can just bind your datagridview to BindingList. It is similar to List, but also implements IBindingList interface (when you set the BindingList object to List, it will return an object implementing IBindingList, so it'll be very similar) Sou you can do: myDataGridView.DataSource = myBindingList; If properties of items on myBindingList change, the result will be reflected on datagridview by default, if the collection changed (some things were added or deleted), you may refresh it using: CurrencyManager cm = (CurrencyManager)this.myDataGridView.BindingContext[myBindingList]; if (cm != null) { cm.Refresh(); } share|improve this answer answered Oct 12 '11 at 9:12 Arie 3,21411531 add a comm

Join them; it only takes a minute: Sign up DataGrid throws IndexOutOfRangeException from CurrencyManager when any cell clicked up vote 3 down vote favorite 3 I have a data grid on a windows form. When I initially update that grid to contain data, and then click on it, I get the below exception. Notably the exception is http://stackoverflow.com/questions/7810149/datagrid-throws-indexoutofrangeexception-from-currencymanager-when-any-cell-clic deep down in the windows handling of the form, and so the exception is caught at the point whereby I launch the form. Please note, I had to tick "Show External Code" in the Call Stack to show the Call Stack below, otherwise it just shows [External Code]. In terms of hunches/troubleshooting steps, thinking that it may have been caused by a message that is fired for the item which was selected and then the item which is now selected, I have tried to .SelectAll(); on the DataGridView after updating the data, this had the same results. The Exception: IndexOutOfRangeException {"Index -1 does not have a value."} The Call Stack: System.Windows.Forms.dll!System.Windows.Forms.CurrencyManager.this[int].get(int index) + 0xa1 bytes System.Windows.Forms.dll!System.Windows.Forms.CurrencyManager.Current.get() + 0x16 bytes System.Windows.Forms.dll!System.Windows.Forms.DataGridView.DataGridViewDataConnection.OnRowEnter(System.Windows.Forms.DataGridViewCellEventArgs e) + 0x101 bytes System.Windows.Forms.dll!System.Windows.Forms.DataGridView.OnRowEnter(ref System.Windows.Forms.DataGridViewCell dataGridViewCell = null, int columnIndex = 1, int rowIndex = 0, bool canCreateNewRow, bool validationFailureOccurred) + 0x218 bytes System.Windows.Forms.dll!System.Windows.Forms.DataGridView.SetCurrentCellAddressCore(int columnIndex = 1, int rowIndex = 0, bool setAnchorCellAddress, bool validateCurrentCell, bool throughMouseClick = true) + 0x59f bytes System.Windows.Forms.dll!System.Windows.Forms.DataGridView.OnCellMouseDown(System.Windows.Forms.DataGridView.HitTestInfo hti, bool isShiftDown, bool isControlDown) + 0x12db bytes System.Window
