Re: enbable disable cehckboxes on checkbox in repeater
did you tried to set the AutoPostBack of property of the checkbox to true?
Re: enbable disable cehckboxes on checkbox in repeater
that problem ahs been resolved in this way
Code:
Private Sub myCheckedChanged(ByVal sender As Object, ByVal e As EventArgs)
Dim chkPkg As CheckBox = DirectCast(sender, CheckBox)
Dim ri As RepeaterItem = DirectCast(chkPkg.NamingContainer, RepeaterItem)
If chkPkg.Checked = True Then
DirectCast(ri.FindControl("single"), CheckBox).Enabled = chkPkg.Checked
DirectCast(ri.FindControl("Double"), CheckBox).Enabled = chkPkg.Checked
Else
DirectCast(ri.FindControl("single"), CheckBox).Checked = chkPkg.Checked
DirectCast(ri.FindControl("Double"), CheckBox).Checked = chkPkg.Checked
DirectCast(ri.FindControl("single"), CheckBox).Enabled = chkPkg.Checked
DirectCast(ri.FindControl("Double"), CheckBox).Enabled = chkPkg.Checked
DirectCast(ri.FindControl("txt_single"), TextBox).Enabled = chkPkg.Checked
DirectCast(ri.FindControl("txt_double"), TextBox).Enabled = chkPkg.Checked
End If
'Dim cb As CheckBox = CType(sender, CheckBox)
'Dim rp As RepeaterItem = CType(cb.NamingContainer, RepeaterItem)
''Dim lb As Label = CType(Repeater1.Items(3).FindControl("Label2"), Label)
'Dim lb As Label
'' lb.Text = "You selected row " & rp.ItemIndex.ToString()
'Dim i As Int32
'Dim cbid As CheckBox
'For i = 0 To Me.Repeater1.Items.Count - 1
' cbid = CType(Repeater1.Items(i).FindControl("single"), CheckBox)
' lb = CType(Repeater1.Items(i).FindControl("Label2"), Label)
' 'lb.Text = "You selected row " & rp.ItemIndex.ToString()
' 'lb.Text = "You selected row " & rep
' If Not (cbid Is Nothing) And cb.Checked = True Then
' If cb.Checked = True Then
' cbid.Enabled = True
' Exit For
' Else
' cbid.Enabled = False
' cbid.Checked = False
' End If
' End If
'Next
End Sub
Private Sub singleCheckedChanged(ByVal sender As Object, ByVal e As EventArgs)
Dim chksingl As CheckBox = DirectCast(sender, CheckBox)
Dim ri As RepeaterItem = DirectCast(chksingl.NamingContainer, RepeaterItem)
If chksingl.Checked = True Then
DirectCast(ri.FindControl("txt_single"), TextBox).Enabled = chksingl.Checked
Else
DirectCast(ri.FindControl("txt_single"), TextBox).Enabled = chksingl.Checked
End If
'DirectCast(ri.FindControl("txt_double"), TextBox).Enabled = chkPkg.Checked
End Sub
Private Sub doubleCheckedChanged(ByVal sender As Object, ByVal e As EventArgs)
Dim chkdouble As CheckBox = DirectCast(sender, CheckBox)
Dim ri As RepeaterItem = DirectCast(chkdouble.NamingContainer, RepeaterItem)
If chkdouble.Checked = True Then
DirectCast(ri.FindControl("txt_double"), TextBox).Enabled = chkdouble.Checked
Else
DirectCast(ri.FindControl("txt_double"), TextBox).Enabled = chkdouble.Checked
End If
'DirectCast(ri.FindControl("txt_double"), TextBox).Enabled = chkPkg.Checked
End Sub
see the code
Code:
'get how many packages hav been selected
Dim c As Int32
Dim str As String
For Each dataItem As RepeaterItem In Repeater1.Items
Dim ckchecked As CheckBox = DirectCast(dataItem.FindControl("chk_packages"), CheckBox)
If ckchecked.Checked Then
Dim chk_single As CheckBox = DirectCast(dataItem.FindControl("single_rate"), CheckBox)
Dim chk_double As CheckBox = DirectCast(dataItem.FindControl("double_rate"), CheckBox)
If chk_single.Checked Then
c = c + 1
ElseIf chk_double.Checked Then
c = c + 1
End If
End If
Next
I need to check at least one package must be selected with either single/double room packages .in above codes nippt it says "NOTHING" when i put break point on this line
Code:
Dim chk_single As CheckBox = DirectCast(dataItem.FindControl("single_rate"), CheckBox)
please reply me if need further desscription
Re: enbable disable cehckboxes on checkbox in repeater
Hello,
Has your ASPX markup changed from what you posted above? I don't see any control called "single_rate" in the ASPX markup for the ItemTemplate.
