if you have a datalist, can disable and enable rows in that datalist with radiobuttons?
Can you explain what do you mean by enable/disable? What kind of info does the datalist contain and why/what kind of info do you want to disable/enable?
im designing an online voting system, so i will have many candidates running for a position.
Lets say i have 5 candidates, that would be 5 rows and each row would have a radiobutton. if you clicked that radiobutton it would disabel that candidate. you could select all candidates until they were all disabled. i would then have a way to enable each candidate if i wanted too.
does that make sense?
Here is a working (but not pretty) version.
<scriptrunat="server">
Dim sourceAsNew Data.DataTable
ProtectedSub Page_Load(ByVal senderAsObject,ByVal eAs System.EventArgs)
IfNot IsPostBackThen
source.Columns.Add("PID",GetType(Integer))
source.Columns.Add("Position",GetType(String))
source.Columns.Add("CID",GetType(Integer))
source.Columns.Add("Candidate",GetType(String))
source.Columns.Add("IsActive",GetType(Boolean))
Dim rowAs Data.DataRow
For iAsInteger = 1To 2
For jAsInteger = 1To 4
row = source.NewRow()
row(0) = i
row(1) ="Position " & i.ToString()
row(2) = j
row(3) ="Candidate " & j.ToString()
row(4) = 0
source.Rows.Add(row)
Next
Next
GV.DataSource = source
GV.DataBind()
EndIf
EndSub
ProtectedSub IsCActive_CheckedChanged(ByVal senderAsObject,ByVal eAs System.EventArgs)
Dim cboxAs CheckBox =CType(sender, CheckBox)
If cbox.Checked =TrueThen
' Disable that row
' I am only disabling the CheckBox as all other
' fields are already in readonly mode
cbox.Enabled =False
EndIf
EndSub
