Solution 1

"Input string was not in a correct format."
Means what it says: the string value you are passing to Convert.ToDecimal is not recognisable as a Decimal number.

Check the content of the drop down list, and see what SelectedValue is returning in the debugger.

droup downlist bind

DataTable dtf = new DataTable();
dt = SelectData();
DataView dv = dt.DefaultView;
dv.RowFilter = "Category='" + s + "'";
if (dv.Count > 0)
{
DataTable ddd = new DataTable();
ddd = dv.Table;
ddlexp.DataTextField = "Planname";
ddlexp.DataValueField = "Amount";
ddlexp.DataSource = dv.Table;
ddlexp.DataBind();
}

Does not mean that the value returned by SelectedValue is a numeric string: it could be null, it could be "1.2.3", it could be anything.
So check it in the debugger and see exactly what it is that you are trying to convert...

Solution 2

Convert.ToDecimal(ddlexp.SelectedValue)

here the selected values is in string format which cannot be converted to decimal make sure that it is not in string format
