Hi all,I have used this code to upload file, but I cannot get the result in Database.

C#

Protected Sub btnsave_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnsave.Click
        If FileUpload1.PostedFile IsNot Nothing Then

            Dim FileName As String = Path.GetFileName(FileUpload1.PostedFile.FileName)



            'Save files to disk

            FileUpload1.SaveAs(Server.MapPath("~/images/" & FileName))

            Dim CN As New SqlConnection("Server=pc5268;uid=sa;pwd=klo;database=MSK2DB")

            Dim qry As String = "insert into tblFiles (QID, Question, QDetail, QFilePath, QFileName) values(@QID, @Question, @QDetail, @QFilePath, @QFileName)"


            Dim SqlCom As New SqlCommand(qry, CN)

            SqlCom.Parameters.Add(New SqlParameter("@QID", DirectCast(TextBox1.Text, Object)))
            SqlCom.Parameters.Add(New SqlParameter("@Question", DirectCast(TextBox2.Text, Object)))
            SqlCom.Parameters.Add(New SqlParameter("@QDetail", DirectCast(TextBox3.Text, Object)))
            SqlCom.Parameters.AddWithValue("@QFilePath", "~/images/" & FileName)
            SqlCom.Parameters.AddWithValue("@QFileName", FileName)
            SqlCom.CommandType = CommandType.Text

            SqlCom.Connection = CN

            Try
                CN.Open()
                SqlCom.ExecuteNonQuery()
            Catch ex As Exception
                Response.Write(ex.Message)
            Finally
                CN.Close()
                CN.Dispose()
            End Try

        End If
    End Sub

Source code:

C#

<asp:ScriptManager ID="ScriptManager1" runat="server">  
     </asp:ScriptManager>
    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>

<asp:TextBox ID="TextBox1" runat="server">

            <asp:TextBox ID="TextBox2" runat="server">

            <asp:FileUpload ID="FileUpload1" runat="server" />

Where I should include this code?

thatraja 5-Dec-13 7:31am

In Page_Load()

Member 10419145 5-Dec-13 8:02am

Thanks for your help. But by doing so the whole page is being refreshed, I donot want that to happen.

When ever u r using the page response's like upload, download, redirect things in update panel surly it will fail so that i have posted the code will help to disable the update panel for given time in(timeout).

OR

try another method to user the <Triggers>
.........................................

<UpdatePanel runat="server">
<contenttemplate>
...
<asp:Button runat="server" ID="myButton" />
...

<Triggers>
<asp:PostBackTrigger ControlID="myButton" />
</Triggers>
