Question

i am trying to write some code behind a webpage to send an email onClick of a button.

i have a text box

<asp:TextBox ID="txtSecEmail" runat="server" Width="189px" 
ontextchanged="txtSecEmail_TextChanged"></asp:TextBox>

i also have a button after that

<asp:Button ID="btnUploadFiles" runat="server" Text="Upload Files"      
    Command="Command"
 CommandArgument="CommandArgument"
 runat="server" onclick="btnUploadFiles_Click"  />

when i try to load the page i get this error

Compilation Error

Line 98:             </td>

Source File: Y:\Prog\NET\web\ClientCenterNew\datauploaddatafiles.aspx Line: 96

i dont understand how it is not a member? and why its saying this?

Answer 1

It is looking for the txtSecEmail_TextChanged method in the codebehind (datauploaddatafiles.aspx.vb). Put that sub routine in the code behind file and rebuild.

Example:

Protected Sub txtSecEmail_TextChanged(ByVal sender As Object, _
        ByVal e As System.EventArgs) Handles txtSecEmail.TextChanged
   'Some Code
End Sub
