this is the grid(rgstatetax) prerender event

}
}
}
Code in UI
protected void ddlCountryTax_SelectedIndexChanged( object sender, EventArgs e ) { long locationId = ddlCountryTax.SelectedItem.Value.AsLong();
ContentAdministrationServiceClient client = null;
List<DCTaxRate> taxRate = null;
try
{

This occurs when the list of values in the dropdown does not include the value being bound to the SelectedValue property. If this is because you have a null value you could get the data adapter to return an empty string when the field is null (if that is the problem) and then insert a value in the dropdown list to match:
<asp:DropDownList ID="dd_bound" runat="server" AppendDataBoundItems="True"> <asp:ListItem Value="" Text="Select one..." /> </asp:DropDownList>Note the AppendDataBoundItems value.
peter : i made appenddatabounditems to true still the same error comingRichard : do you know what the value being bound to is? is it null or another value which is not in the list?peter : reading the country collection/ list beyond its bound into the dropdown.Thats wat hapened here ..Any way thanks 4 the replay -
