Asp.net - Customvalidator: Check If Radiobuttonlist Contains A Selected Item?
May 17, 2010
I have a radiobuttonlist with two items, Yes or No. The radiobuttonlist control has a customvalidator that needs a servervalidation function and a javascript clientvalidationfunction. Could you help me? The function in this message works but only when i actually have choosen one of the two listitems, when no listitem is selected the validation skips my radiobuttonlist control.
function ValidateRadioButtonList(source, arguments) {
var RBL = document.getElementById(source.controltovalidate);
var radiobuttonlist = RBL.getElementsByTagName("input");
var counter = 0;

I have 20 RadioButtonLists on a page.
I need to create a validation method to ensure that at least one of these RadioButtonLists has an item selected.
What kind of validation would I need to use for this?

I have a form with contains, among others, a TextBox called "wmi_cell_phone" and a RadioButtonList "wmi_send_sms". Basically, I need to create a validator that checks whether the value of the selected radio is "Y". If this is the case, then it checks if the TextBox value is empty or not. If it is empty, then it should notify the user to enter a value.

Just started on vb.net
I have a combo box with "yes" and "no" with i select Yes i want the label2 to change the text to "yes" likewise with "no"
I've tried to code it in a logical way as possible but it just doesn't works except for the "wtf" so i think that overall my code is correct but the way i want to retrieve the selected item from combo box is wrong.

I got this in another post <asp:RadioButtonList runat=server ID="rd" SelectedValue='<%# Bind("sex").GetType() == typeof(DBNull) ? null : Bind("sex") %>'
<asp:ListItem Text="male" Value="1"></asp:ListItem>
<asp:ListItem Text="female" Value="2"></asp:ListItem>
</asp:RadioButtonList>
Is this a correct syntax?? If yes can someone please give the VB version of it??
SelectedValue='<%# Bind("sex").GetType() == typeof(DBNull) ? null : Bind("sex") %>'

I'm having some difficulty with a sorted & grouped listbox in WPF vb.net 3.5 that has an items source bound to an ObservableCollection.
What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.
[code]...
As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?

Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString

I am making a password program that remembers what the password is for and what the password is. I have two listboxes: 'listbox1' for what the password is for, and 'listbox2' for the password. I also have a remove button. I would like it so when you press the remove button, the selected item in listbox1 is removed and the password in listbox2 is also deleted. The passwords are stored in two settings: what, and pw. The items that will be deleted will have the same value. By value i mean they will be the same number item. E.G. the 1st item, or the 3rd item in the list.

In my Windows Form I have a ComboBox that is filled by a Stored Procedure with a list of names. I have the Combobox set for AutoComplete to "Suggest" and From "ListItems". When a user starts to type in and the AutoComplete does not find any matches in the listitems the user can tab out of the ComboBox and leave what they typed in the combobox even though it is not one of the Valid Items. Is there a way to check the Comboxbox to make sure of of the selected Items has been selected?

I have a CustomValidator that checks if text entered in textboxes matches certain fields in a database. This was all working great before, but I have modified my page quite a bit since then and it is no longer working. I didn't think I changed anything that would affect this, but apparently I did. All my other validators (required field validators) are working correctly, but my CustomValidator isn't responding.So anyway, here is my code:
CustomValidator:
<asp:CustomValidator ID="CustomValidator1" runat="server" ControlToValidate="txtCoursePrefix" ErrorMessage="Course number is already taken."></asp:CustomValidator>
[code]....
Everything is working up until CustomValidator1.SetFocusOnError = True and args.IsValid = False. I have tested the If statement and it's working correctly, it returns true and anything else I put inside of it executes.

I know this has been asked a lot, but I have a server-side custom validator that is not being fired, and I cannot find why (also, I've copied examples that work from other places and cannot make it work...)
The code:
<asp:CustomValidator ID="MyValidator" runat="server" ErrorMessage="My error message" OnServerValidate="MyValidator_OnServerValidate" />
Validate function
[Code]...
EDIT 2: Added a Page.validate() on my button code, and it does not call the server side of the validator.Also, the custom validator is being called (at least the client/javascript side of it, but not the server side)

Writing a custom validator for a dropdownlist that is using autopostback. Seems to ignore the validation altogether. Why is it ignored and is there an easy fix? Note I did not use ControlToValidate
asp.net:
<asp:UpdatePanel ID="updatePanel" runat="server" UpdateMode="Conditional" Visible="true" RenderMode="Inline">
<ContentTemplate>
<asp:DropDownList ID="ddlCommandAssign" runat="server" AutoPostBack="true">
</asp:DropDownList>
[code]....
For debugging purposes, I want it to fail every time.It doesn't seem to be executing the behind code at all. For debugging, I added the line response.redirect("dummy.html") ... which never gets called, which also indicates (I think) that the validator never gets called.

i have a sub that checks all drives on a computer;
Dim getInfo As System.IO.DriveInfo()
getInfo = System.IO.DriveInfo.GetDrives
For Each info As System.IO.DriveInfo In getInfo
TextBox1.Text = TextBox1.Text & info.Name & vbCrLf
Next
this shows all drives in textbox1. now if i select the drive i want, i can then check the free & total space with this sub;
Dim cdrive As System.IO.DriveInfo
cdrive = My.Computer.FileSystem.GetDriveInfo(TextBox1.SelectedText)
TextBox2.Text = TextBox1.SelectedText & " has " & cdrive.TotalSize / 1024 / 1024 / 1024 & "gb total space" & vbCrLf
TextBox2.Text = TextBox2.Text & "and " & cdrive.TotalFreeSpace / 1024 / 1024 / 1024 & "gb free space"
all this is good if i select the drive i want to check. but if i only click the drive, since no text is selected, the second sub does not work.is there a way to check at which index the cursor is, grab the item of the index, and pass it to the sub so i don't have to select the text itself?
