asp.net,vb.net , Gridview items not populating correctly


Gridview items not populating correctly

Question:

Tag: asp.net,vb.net

I have data I am trying to input into a gridview. I am looking up the number of rows for the gridview and adding data into them like this:

My "test" however does not get populated into the Submitted and Variance BoundFields in the Gridview. All that populates is the Company. Shouldn't "test" also populate in those other two columns?

Private Sub BindGrid()

    Dim dt As New DataTable
    dt.Columns.Add("Company")
    dt.Columns.Add("Submitted")
    dt.Columns.Add("Variance")
    gvTally.DataSource = dt


    Dim da As SqlClient.SqlDataAdapter
    Dim strSQL2 As String
    Dim Response As String = ""

    strSQL2 = "SELECT [Company] FROM [Monetra].[dbo].[tbl_MonetraLogins]"
    da = New SqlClient.SqlDataAdapter(strSQL2, System.Configuration.ConfigurationManager.AppSettings("MainConnectionString").ToString)
    da.Fill(dt)

    Dim dr As DataRow

    For i As Integer = 0 To gvTally.Rows.Count - 1

        dr = dt.NewRow
        dr.Item("Company") = dt.Rows(i).Item("Company")
        dr.Item("Submitted") = "test"
        dr.Item("Variance") = "test"

        dt.Rows.Add(dr)
    Next

    gvTally.DataSource = dt
    gvTally.DataBind()

End Sub

Here is my ASP Grid:

<asp:GridView ID="gvTally" runat="server" EnableModelValidation="True" 
                    AllowSorting="True" class="table table-condensed table-striped table-bordered table-hover no-margin" AutoGenerateColumns="False" Font-Size="Small">
                    <Columns>
                        <asp:BoundField DataField="Company" HeaderText="Company" >
                        <ItemStyle Width="180px" />
                        </asp:BoundField>
                        <asp:BoundField DataField="Submitted" HeaderText="Submitted" />
                        <asp:BoundField DataField="Variance" HeaderText="Variance" />
                        <asp:TemplateField HeaderText="Action" ShowHeader="False">
                            <ItemTemplate>
                                <asp:Button ID="Button1" runat="server" CssClass="btn btn-success btn-small hidden-phone" Text="View" CommandName="View" />
                            </ItemTemplate>
                            <ItemStyle Width="60px" />
                        </asp:TemplateField>
                    </Columns>
                </asp:GridView>

Answer:

Try this vb code behind, then comment out my test

Private Sub BindGrid()

    Dim dt_SQL_Results As New DataTable

    '' Commenting out to use test data as I have no access to your database
    'Dim da As SqlClient.SqlDataAdapter
    'Dim strSQL2 As String
    'Dim Response As String = ""
    'strSQL2 = "SELECT [Company] FROM [Monetra].[dbo].[tbl_MonetraLogins]"
    'da = New SqlClient.SqlDataAdapter(strSQL2, System.Configuration.ConfigurationManager.AppSettings("MainConnectionString").ToString)
    'da.Fill(dt_SQL_Results)
    '' Commenting out to use test data as I have no access to your database

    '' Comment this block out after you test and uncomment the above code block
    dt_SQL_Results.Columns.Add("Company")
    Dim dr_SQL_Results As DataRow
    For i As Integer = 0 To 5
        dr_SQL_Results = dt_SQL_Results.NewRow
        dr_SQL_Results.Item("Company") = "Company " & i
        dt_SQL_Results.Rows.Add(dr_SQL_Results)
    Next
    'gvTally.DataSource = dt_SQL_Results
    'gvTally.DataBind()
    '' Comment this block out after you test and uncomment the above code block

    Dim dt As New DataTable
    dt.Columns.Add("Company")
    dt.Columns.Add("Submitted")
    dt.Columns.Add("Variance")

    Dim dr As DataRow
    For i As Integer = 0 To dt_SQL_Results.Rows.Count - 1
        dr = dt.NewRow
        dr.Item("Company") = dt_SQL_Results.Rows(i).Item("Company")
        dr.Item("Submitted") = "test"
        dr.Item("Variance") = "test"
        dt.Rows.Add(dr)
    Next

    gvTally.DataSource = dt
    gvTally.DataBind()

End Sub
