Inserting multiple single checkbox controls text into a single column in db

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 table columns with several checkboxes , kinda like Check all the conditions that apply , but for several criterias, so I am guessing probably a string builder or array? Please help with my code below:
code
 /* Concatenate every checkbox text and textfield that apply! */
 /*------------------------------------------------------------------------------------------------------*/
 StringBuilder sbSpecificEvents = new StringBuilder();
 if (eventdetailsSSI1.Checked)
 {
 sbSpecificEvents.Append(eventdetailsSSI1.Text + ",");
 }
 if (eventdetailsSSI2.Checked)
 {
 sbSpecificEvents.Append(eventdetailsSSI2.Text + ",");
 }

• Guffa: Not code review, as there is no code... This should go to StackOverflow instead.
• ricko: What do you mean by code?
• Guffa: I mean code. There was no code to get the values from the checkboxes before you edited the question, so there was nothing to review.

Answer 1

I'm not sure that it's the best choise to store the items as text in the database, and to store them in a single field, but that's a different matter...

You can put the checkboxes in an array and loop over it. Put the selected text in a list, and join it:

Checkbox[] checkboxes = new Checkbox[] { eventCriteria1, eventCriteria2, ... , eventCriteria18 };
List<string> checked = new List<string>();
foreach (Checkbox checkbox in checkboxes) {
 if (checkbox.Checked) {
 checked.Add(checkbox.Text);
 }
}
string checkedText = String.Join(", ", checked);
