check/clear checkboxes

Posted By:      Posted Date: September 23, 2010    Points: 0   Category :ASP.Net

I'm trying to make a custom control that checks or clears all checkboxes on a page simultaneously when a designated checkbox is checked or cleared. I have this (non-working) code so far:

    Public Shared Sub CheckUncheck(ByVal container As Control, ByVal blnChecked As Boolean)
        Dim intCount As Integer = 0, intTotal As Integer = container.Controls(0).Controls.Count
        Do While intCount < intTotal
            If container.Controls(0).Controls(intCount).GetType = GetType(CheckBox) Then
                Dim chk As CheckBox = CType(container.Controls(0).Controls(i), CheckBox)
                chk.Checked = blnChecked
            End If
            intCount += 1
    End Sub

The line that's giving me trouble is the one starting with "If container.Controls(0)"... Bad syntax that gives me this message: Operator '=' is not defined for types System.Type and System.Type. What I'm trying to do, of course, is test to see if the control is a checkbox; and if it is, either check or clear it depending on the value of blnChecked.

Using a CompareValidator to check input is a valid date

The CompareValidator can do more than just compare two controls. You can also compare it against several of the main .net data types such as Date, Integer, Double and Currency.

To do this you would set Operator="DataTypeCheck" and instead of setting the ControlToCompare or ValueToCompare attributes as you normally would you use the Type="Date" (or any of the data types I have listed above).

Check All with JQuery and a Asp.Net GridView

Display a Grid on the screen with a checkbox in each row. At the bottom of the page have "Check All" button.

Typically if I need to do anything interesting I use a template column. So my GridView will look like the one below (most other columns removed for readability). The only interesting point to note is the CssClass="ApprovalCheckBox" in the CheckBox ItemTemplate.

check box control


Hi ,

I have a three check box in my web form ,i need to choose only one check box, if i choose one check box

another 2 check box automatically unchecked

can i use jquery for check box

I thought this would be simple... Trying to create a login does an ajax check before submit


I have the standard .net login control that is working.  (Still learning .net after 15yrs of classic)

What I want to do is OnButtonClick run a javascript function (to do an ajax call to the db to check if login is valid or not) and if it returns true, then submit the form normally, else don't submit. The piece that I can't figure out, is how to correctly override the default click even to hit my JS routine and then submit the form properly afterwards.

Thanks ahead of time

How to check for null/empty strings on dynamic objects?


What is the proper way to check for null or empty strings on dynamic objects? This is the only solution I've found so far:

if (admin.PasswordHash.GetType() == typeof(DBNull) || admin.PasswordHash == string.Empty)

If the field is null, the object returned is DBNull.Value, but if the field is empty string, it's return as a System.String object. This makes it impossible to do regular "admin.PasswordHash == DBNull.Value" check, as that will fail whenever the field has been set to empty string. Is my example the right (and only) way to go?

Checkboxes from data table


I have a data table that contains some values for Certifications.  This table can be updated in a different part of my application.  On the web page I am currently working on, I would like to have check boxes appear for every value in the data table.  I have been struggling with this trying to use a For Each loop and I cannot get it to work for anything.  Any suggestions? 

I am using the following Razor syntax to obtain my data (I know this works because I can display it in a WebGrid):


var db = Database.Open("MyConn");

Automatically redirect to HTTPS and check if SSL is active



I've set in the web.config:

    <!-- User Authentication -->
    <authentication mode="Forms">
      <forms loginUrl="~/Page/View/Content/Login.aspx" timeout="2880" requireSSL="true" />

This works fine. If there is no ssl connection, the login form doesn't continue. But I would like to check if ssl is active (in codebehind) and, if it's possible, to automatically the user to the https page if he's currently on http. (I could do this job by manually redirect with page.response("https://url.../login.aspx"); but this is not really generic. For example if the webapp is moved to another domain it doesn't work anymore... I'm looking for something like: FormsAuthentication.RedirectWithSSL(); or so... :D)

 Hi all, and thanks a lot for the replies since now. I have a new question :
