Помогите пожалуйста! Поискала в Интернете, нашла кое-что, но не работает UpdateCommand.
Вот мой код:
gridview:

<asp:GridView ID="GridView3" runat="server" AutoGenerateColumns="False" DataKeyNames="ID_CLIENT" DataSourceID="SqlDataSource3">
<Columns>
<asp:BoundField DataField="ID_CLIENT" HeaderText="ID_CLIENT" ReadOnly="True"
SortExpression="ID_CLIENT" />
<asp:BoundField DataField="NUME" HeaderText="NUME" SortExpression="NUME" />
<asp:BoundField DataField="PRENUME" HeaderText="PRENUME"
SortExpression="PRENUME" />
<asp:BoundField DataField="PATRONIMIC" HeaderText="PATRONIMIC"
SortExpression="PATRONIMIC" />
<asp:BoundField DataField="TELEFON" HeaderText="TELEFON"
SortExpression="TELEFON" />
<asp:BoundField DataField="NR_PASAPORT" HeaderText="NR_PASAPORT"
SortExpression="NR_PASAPORT" />
<asp:BoundField DataField="EMAIL" HeaderText="EMAIL" SortExpression="EMAIL" />
<asp:BoundField DataField="VIRSTA" HeaderText="VIRSTA"
SortExpression="VIRSTA" />
<asp:CommandField HeaderText="Edit" ShowEditButton="True" ShowHeader="True" />
</Columns>
</asp:GridView>

вот datasource:

<asp:SqlDataSource ID="SqlDataSource3" runat="server"

ConnectionString="<%$ ConnectionStrings:ConnectionStringora %>"
ProviderName="<%$ ConnectionStrings:ConnectionStringora.ProviderName %>"
SelectCommand="SELECT "ID_CLIENT", "NUME", "PRENUME", "PATRONIMIC", "TELEFON", "NR_PASAPORT", "EMAIL", "VIRSTA" FROM "CLIENTI""
UpdateCommand="update ""CLIENTI"" set "NUME"=:NUME where "ID_CLIENT"=:Original_ID_CLIENT">
<UpdateParameters>
<asp:Parameter Name="Original_ID_CLIENT" Type="int32" />
<asp:Parameter Name="NUME" Type="string" Size="200" />

</UpdateParameters>
</asp:SqlDataSource>

вот ошибка:
ORA-01036: illegal variable name/number

Извиняюсь за это:
UpdateCommand="update ""CLIENTI"" set "NUME"=:NUME where "ID_CLIENT"=:Original_ID_CLIENT">

на самом деле:
UpdateCommand="update CLIENTI set NUME=:NUME where ID_CLIENT=:Original_ID_CLIENT">

Про Original прочитала в Интернете :(
