I want to create a grid view with one column containing empty textboxes where the user can input a number (quantity), some regular columns and a column dedicated to images.

I have the following code in C#:

```
    Label_Error.Visible = false;

    DataTable dt = new DataTable();
    dt.Columns.Add("Quantity", typeof(TextBox));
    dt.Columns.Add("Book ID", typeof(int));
    dt.Columns.Add("Name", typeof(string));
    dt.Columns.Add("Author", typeof(string));
    dt.Columns.Add("Description", typeof(string));
    dt.Columns.Add("Price", typeof(float));
    dt.Columns.Add("Currency", typeof(string));
    dt.Columns.Add("Image", typeof(string));

    DataRow row1 = dt.NewRow();
    row1["Quantity"] = new TextBox();
    row1["Book ID"] = 1;
    row1["Name"] = "Moby Dick";
    row1["Author"] = "Herman Melville";
    row1["Description"] = "Adventure Book";
    row1["Price"] = 10;
    row1["Currency"] = "EUR";
    row1["Image"] = ResolveUrl("~/Images/Logo.png");
    dt.Rows.Add(row1);

    GridView_Products.DataSource = dt;
    GridView_Products.DataBind();

```

This is what I am getting at the output:

As you can see, the quantity column of empty textboxes is not being shown and the image is not being shown neither. How can I solve these two problems please?

**Update**

This is the code in the .aspx page:

```
<asp:GridView ID="GridView_Products" runat="server" BackColor="White" 
            BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3" 
            HorizontalAlign="Center">
            <FooterStyle BackColor="White" ForeColor="#000066" />
            <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" 
                HorizontalAlign="Center" />
            <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
            <RowStyle ForeColor="#000066" HorizontalAlign="Center" />
            <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
            <SortedAscendingCellStyle BackColor="#F1F1F1" />
            <SortedAscendingHeaderStyle BackColor="#007DBB" />
            <SortedDescendingCellStyle BackColor="#CAC9C9" />
            <SortedDescendingHeaderStyle BackColor="#00547E" />
        </asp:GridView>

```
