Hi, I am trying to edit/update the gridview without using edit and update buttons. I am not sure how to achieve this yet. I converted the vb code below from c# and got a compilation error. Can someone help? Thank you!


Compilation Error

Compiler Error Message: BC30456: 'GridView1_RowCommand' is not a member of 'ASP.itrequest_aspx'.

Source Error:

        Dim txtone As TextBox = DirectCast(gvr.FindControl("txtone"), TextBox)
        'update to database

Your code behind does not have "GridView1_RowCommand" defined.
One possible solution is to delete OnRowCommand event from aspx file:
Replace:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
             BackColor="White" BorderColor="#DEDFDE" BorderStyle="None" BorderWidth="1px" 
             CellPadding="4" ForeColor="Black" 
             GridLines="Vertical" OnRowCreated="GridView1_RowCreated" OnRowCommand="GridView1_RowCommand">

Open in new window

with:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
             BackColor="White" BorderColor="#DEDFDE" BorderStyle="None" BorderWidth="1px" 
             CellPadding="4" ForeColor="Black" 
             GridLines="Vertical" OnRowCreated="GridView1_RowCreated">

Open in new window

Thanks Miguel! The error is gone. the problem now is when I entered something in the textbox, the DirectCast does not cast any value at all. Any suggestions? Thank you.
