incorrect syntax near nvarchar in gridview - asp.net

Question

I have a problem about the updating a column of my gridview; when I try to update the field I get this error:
Incorrect syntax near 'nvarchar'.
Must declare the scalar variable "#pid".
Here is a piece of my code:
<asp:GridView ID="GridView1" runat="server" name="gd" Height="100px"
Width="435px" AutoGenerateColumns="False" DataKeyNames="pid" DataSourceID="SqlDataSource1" >
<Columns>
<asp:CommandField ShowEditButton="True" ShowSelectButton="True" />
<asp:BoundField DataField="pid" HeaderText="pid"
SortExpression="pid" ReadOnly="True" />
<asp:BoundField DataField="name" HeaderText="name"
SortExpression="name" />
<asp:BoundField DataField="hoghoghe rozane" HeaderText="hoghoghe rozane"
SortExpression="hoghoghe rozane" />
<asp:BoundField DataField="paye" HeaderText="paye"
SortExpression="paye" />
<\Columns>
<asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
UpdateCommand="UPDATE [post] SET [name] = #name, hoghoghe_rozane = #hoghoghe_rozane, [paye] = #paye WHERE (pid = #pid)" >
<UpdateParameters>
<asp:Parameter Name="name" Type="String" />
<asp:Parameter Name="hoghoghe_rozane" Type="Int32" />
<asp:Parameter Name="paye" Type="Int32" />
<asp:Parameter Name="pid" Type="String" />
</UpdateParameters>
</asp:SqlDataSource>

Answer 1

chek this out : same problem
it says you must change [hoghoghe rozane] into [hoghoghe_rozane]
Update :::
1.Make sure that the type of pid field in database
2.fields should not have spaces in your tables
3.alias should not have spaces too
try this code :
<asp:GridView ID="GridView1" runat="server" name="gd" Height="100px"
Width="435px" AutoGenerateColumns="False" DataKeyNames="pid" DataSourceID="SqlDataSource1" >
<Columns>
<asp:CommandField ShowEditButton="True" ShowSelectButton="True" />
<asp:BoundField DataField="pid" HeaderText="pid"
SortExpression="pid" ReadOnly="True" />
<asp:BoundField DataField="name" HeaderText="name"
SortExpression="name" />
<asp:BoundField DataField="hoghoghe_rozane" HeaderText="hoghogheRozane"
SortExpression="hoghoghe_rozane" />
<asp:BoundField DataField="paye" HeaderText="paye"
SortExpression="paye" />
<\Columns>
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
UpdateCommand="UPDATE [post] SET [name] = #name, hoghoghe_rozane = #hoghoghe_rozane, [paye] = #paye WHERE (pid = #pid)" >
<UpdateParameters>
<asp:Parameter Name="name" Type="String" />
<asp:Parameter Name="hoghoghe_rozane" Type="Int32" />
<asp:Parameter Name="paye" Type="Int32" />
<asp:Parameter Name="pid" Type="String" />
</UpdateParameters>
hope that would work.
