Question

I need to insert multiple checkbox text into a column in a mssql database,
I could use a single checkbox list and make this thing easier, however,
the requirements are to display separate html rows and columns with several checkboxes ,
kinda like Check all the conditions that apply design , but for several criterias, so I am guessing probably a string builder or array will do so I am attempting the following code but there is gotta be a better cleaner way than manually doing this for each checkbox?

Please help with my code below:

asp.net page
<td>
            &nbsp;
            <span style="color: #FF0000">*</span> Specify Criteria Used (check all that apply)<br />
&nbsp;<span style="text-decoration: underline">Signs &amp; Symptoms<br />
            </span>
            <br />
            <asp:CheckBox ID="eventCriteria1" runat="server" 
                Text="Purulent drainage or material" />

You need to put the CheckBoxes in some sort of a container like a Panel or PlaceHolder, and then you can do this:

ASPX:

<asp:Panel ID="Panel1" runat="server">
    <asp:CheckBox ID="chk1" runat="server" Text="..." />
    ...
</asp:Panel>

Code-behind for ASP.NET 3.5 and above:

foreach (CheckBox chk in Panel1.Controls.OfType<CheckBox>())
{
    if (chk.Checked)
    {
        //update parameter
        cmd.Parameters["@eventCriteria"].Value += String.Format("{0},", chk.Text);
    }
}

//you'll probably need to trim the trailing comma too
cmd.Parameters["@eventCriteria"].Value = cmd.Parameters["@eventCriteria"].Value.TrimEnd(',');

Code-behind for ASP.NET 2.0 and earlier:

foreach (Control ctrl in Panel1.Controls)
{
    if (ctrl is CheckBox)
    {
        CheckBox chk = (CheckBox)ctrl;
        if (chk.Checked)
        {
            //update parameter
            cmd.Parameters["@eventCriteria"].Value += String.Format("{0},", chk.Text);
        }
    }
}

//you'll probably need to trim the trailing comma too
cmd.Parameters["@eventCriteria"].Value = cmd.Parameters["@eventCriteria"].Value.TrimEnd(',');
