Unable to cast object of type 'System.Data.DataRowView' to type 'System.IConvertible'

how can i solve it ?

Please help

Answer 1

It looks like your ddlDivisionId.SelectedValue is returning a DataRowView. I assume you bound a DataTable or similar to your dropdown list (assuming that is what we are looking at).

In this case you will need to treat the ddlDivisionId.SelectedValue as a DataRowView (probably casting to that object first) to get the value out of it... I assume something like:

int i = Convert.ToInt32(((DataRowView)ddlDivisionId.SelectedValue)["id"]);

Here you should replace "id" with whatever the name of your field is in your datatable that you want to get out as an integer.

Answer 2

int i = Convert.ToInt32(ddlDivisionId.SelectedValue.ToString());

add .ToString in last it will work
