.txt contents inside of table

I'm trying to display the contents of a text file in a table. I've got it to successfully read the text file, and display the .txt file contents in a div, but it throws an error when I try to display the contents in a table.

Am I doing something wrong?

Here's my code-behind:

protected void btnUpld_Click(object sender, EventArgs e)
{
    Stream theStream = file1.PostedFile.InputStream; 
    //file1 is an asp:FileUpload on .aspx

    using (StreamReader viewer = new 
           StreamReader((Stream)file1.PostedFile.InputStream))
    {
        while (viewer.Peek() > 0)
        {
            string txtskip = viewer.ReadLine();
            Table1.InnerHtml += txtskip; 
            //Table1 is the table i'm wanting to put the results in on my .aspx
         }
    }
}

This code should help you

 protected void btnRender_Click(object sender, EventArgs e)
{
    using (StreamReader viewer = new StreamReader((Stream)file1.PostedFile.InputStream))
    {
        TableRow tr;
        TableCell tc;
        while (viewer.Peek() > 0)
        {
            string txtskip = viewer.ReadLine();
            //   Table1.InnerHtml += txtskip; //Table1 is the table i'm wanting to put the results in on my .aspx
            tr = new TableRow();
            tc = new TableCell();
            tr.Cells.Add(tc);
            Table1.Rows.Add(tr);
            tc.Text = txtskip;
        }
    }
}

Thanks,

You really shouldn't use a text file to load content like that. Your bound to run into issues, because sooner or later access to that file will be locked. You can negate this risk by loading the contents into Cache and loading it from there.

Following the advice above, you would modify the example below to retrieve the text from Cache, but for the sake of clarity, and to answer your initial question, this example loads it directly form the file:

using (var reader = new StreamReader("bla.txt"))
{
    //use the object initializer to prepare a new literal control
    var litCtrl = new Literal 
    { 
        Mode = LiteralMode.PassThrough, 
        Text = string.Format("<table>{0}</table>", reader.ReadToEnd()))
    }

    //use a literal control to display the table on the page
    pnlContainer.Controls.Add(litCtrl);
}

there is no such property as Innerhtml for table control. you need to assign your text to a column in a row of your table.

you code should be like this

<asp:Table ID="Table2" runat="server">
    <asp:TableRow ID="TableRow1" runat="server">
        <asp:TableCell ID="TableCell1" runat="server">
        This is Cell 1
        </asp:TableCell>
        <asp:TableCell ID="TableCell2" runat="server">
        This is Cell 2
        </asp:TableCell>
    </asp:TableRow>
</asp:Table>

Now on the server side you can write

TableCell1.Text=somestring;
TableCell2.Text=anotherstring;

You can do something like this.

You can place a LiteralControl inside the td where you need your data to be populated. Then

while (viewer.Peek() > 0)
                {
                    string txtskip = viewer.ReadLine();
                    yourLiteral.text += txtskip; 
                }
