CheckBoxList

How do I capture multiple values from a checkboxlist that are submitted?

Code:

foreach( ListItem Citem in CheckBoxList1.Items )
{
    if( Citem.Selected )
        <s>// DO WHAT U WANT...</s>
}

HTH.

I added this:

Dim Citem As ListItem
Dim myHolder
Dim cblRooms As CheckBoxList = myCatHolder2.FindControl("chkRooms")
For Each Citem In cblRooms.Items
                    If Citem.Selected Then
                        myHolder = Citem
                    End If
Next
dbComm.Parameters("rooms").Value = myHolder.ToString

It still only takes the last value checked. Am I missing something? If I add Response.Write(Citem) it displays all items checked in one long string.

Stu,

The reason that it is only taking the last item is that each time you are going through your loop you are setting "myHolder" to a new value, not appending it to the current value. Try replacing:

myHolder = Citem

with:

myHolder += Citem

and see if that helps.

You may have to add a "<br>" if you don't want them to all be on the same line.

That worked.

Thank you.

Hi, I tried to test your code but when i change myHolder += citem It giving me the following error

Operator '+' is not defined for typed "System.Object" and "System.Web.UI.WebControls.ListItem"

Something is off. Post your code block here. Can't really tell from just the error.

This is my code to loop the checkboxlist. But I having error at myHolder += citem

Dim Citem As ListItem
        Dim myHolder

        For Each Citem In cbl_Codes.Items
            If Citem.Selected Then
                myHolder += Citem
            End If
        Next

thanks rstelma, now i can retrieve the selected value. But it in one whole line. I understand that katsarosj mention about "<br>". Can i store it in array? or other methods? so i can insert into database easily. Thanks

You can put them into an array but you will have to loop through the values at some point anyway. Check the code at this post:

As you are looping through the values you can just put them in the database at that time.
