Issue accessing textbox controls nested within a DetailsView within an UpdatePanel

I have a couple of textboxes nested with a detailsview, within an updatepanel.  When I try and access them from the code behind, it returns a null value as if they don't exist.  Can't figure out why that would be.ASPX code is: <asp:UpdatePanel ID="upSpecificShout" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true" > <ContentTemplate> <asp:DetailsView ID="dvSingleShout" DataSourceID="sdsSingleShout" runat="server" AutoGenerateRows="false" OnDataBound="SetDVIcons" HeaderStyle-CssClass="noDisplay" > <EmptyDataTemplate> <p class="Watermark"> The panel on the left shows a list of everything you've shouted. (Your replies to other shouts are highlighted in blue/green.) </p> <p class="Watermark"> This right hand panel will show specific shouts with a list of replies etc.. Just do a little click on a shout title to display more detail here. </p> <p class="Watermark">

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).

Accessing the different controls inside a GridView control

how we can access a particular control which resides inside a GridView control. In this article I will show you how you can access different controls inside a GridView control. We will see how we can access a TextBox control, a DropDownList control and a ListBox control. If you are working with ASP.NET 1.X then you might want to check out my article Accessing Different Controls Inside a DataGrid.

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

Can anybody let me know the right way of doing this?



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?

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 :

I prepared a simple instant messaging system for my web site and i would like to learn which visitor (registered member) is at which page of my site.
