Question

I have an html table in an aspx page (C#) that has columns like

 1.CheckBox  2.Text  3.Text  4.TextBox

I want to iterate through the table one row at a time and process (run a stored procedure based on column2) based on whether the checkbox is checked or not. How will I be able to do that?

Assuming you’re using the Table server control then it’s just:

foreach (TableRow row in table.Rows)
    {
        var checkBox = (CheckBox)row.Cells[0].Controls[0]; //Assuming the first control of the first cell is always a CheckBox.

        if (checkBox.Checked)
        {
            var col2 = (TextBox)row.Cells[1].Controls[0];

            /* Do Stuff With col2 */
        }
        else
        {
            /* Do Stuff */
        }
    }

If you’re using just a regular html table (with runat=”server”) as well as html form controls then just change TableRow to HtmlTableRow, CheckBox to HtmlInputCheckBox, and TextBox to HtmlInputText. All of those controls are in the System.Web.UI.HtmlControls namespace.
