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.

SqlCommand.ExecuteNonQuery() returns -1 when doing Insert / Update / Delete

Sometimes you end up with a return value of -1 when using the SqlClient.SqlCommand.ExecuteNonQuery method.

Why is that?

Well, the ExecuteNonQuery method is there for statements for changing data, ie. DELETE / UPDATE /INSERT, and the returned value are the number of rows affected by that statement.

When checking the documentation we can see that there are some conditions that return -1.

For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command.

When a trigger exists on a table being inserted or updated, the return value includes the number of rows affected by both the insert or update operation and the number of

rows affected by the trigger or triggers. For all other types of statements, the return value is -1. If a rollback occurs, the return value is also -1.

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?

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)
