Index was out of range. Must be non-negative....

Hi,

I get this error :

Code:

---

Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

---

Error is on this line:

Code:

---

string rowID;

rowID = DataGridSpirits.DataKeys[e.Item.ItemIndex].ToString();

---

I have a datagrid, i have a delete and update buttons. This error occurs on both of these events. SOmething to do with returning the row number. It worked earlier, i didn't change anything???

Any help greatly appreciated.

Sounds silly but have you set a DataKeyField for the DataGrid?

If you have could you post the full method that handles the update and also the DataGrid declaration.

Additionally, make sure your code is only executing on a Row or AlternatingRow and not on the headers or footers.

Test the value of e.Item.ItemIndex before you attempt to use it

Thanks to both of you!

For some bizarre reason the DataKeyField was deleted from my webForm, probably due to my clumsyness. Anyway all working now! :)

Thanks
