How to check if a component has an handler

Posted By:      Posted Date: September 24, 2010    Points: 0   Category :ASP.Net
 

Hi guys...


Hope someone could help me on this.

I'm trying to check if the component already has the event...

In my example here, I would like to know if the CollapsiblePanel already has the expandComplete handler before I add the event

   

var currentBehavior = null;
var allBehaviors = Sys.Application.getComponents();

for (var loopIndex = 0; loopIndex < allBehaviors.length; loopIndex++) { currentBehavior = allBehaviors[loopIndex]; if (currentBehavior.get_name() == "CollapsiblePanelBehavior") { //checking will be put here currentBehavior.add_expandComplete(CollapsiblePanel_Event);
        }
}


Thanks In Advance,


Philip

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.

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

  

Hello,

I've set in the web.config:

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


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)

Sorry for my poor english, and let me know if i should explain more clearly :)

Error Registering COM+ Component

  
Hi All,

I am experimenting with using EnterpriseServices. I created a component, created the SNK file, compiled the DLL. In the assemblyinfo.vb file, I added '<Assembly: AssemblyKeyFile("c:\key.snk")> '.
I created a new package in COM+, When I attempt to add the .dll to the package i get:

An error occured while processeing the last operation.
Error Code 80020009 - Exception ocurred.

The eventlog may contain additional troubleshooting information.

Here is the Event log:

Creating Event Handler in Code behind

  

Hi, so I have a control that is created in the code behind and generates fine but I can't figure out how to create an event handler for it.  I've found plenty of examples for it in C sharp, but none of them seem to apply to VB.  What I want to do is essentially this:

myDropDownList.SelectedIndexChanged = "Event to do here"

but it doesn't seem to work for me.

Any suggestions are appreciated.
