Forms Data Controls :: Create A Customized WebControl.QueryStringParameter?
Jan 28, 2011[Code]....
My question is: how can i create my own parameter based upon the QueryStringParameter?
Example:
[Code]....
I now called it QueryStringGuidParameter.
The purpose of this is: I'm not sending any querystring's via the aspx?querystring other thasn aspx?guid={guid identifier}.I hope my code below explains it al little bit.
[Code]....
A soon as a page Redirects f.i. with this example
[Code]....
Instead of calling Response.Redirect i call the Redirect i created. This transforms the querystring in a session with a guid and parameter. The Redirect only sends the guid in the querystring. and the receiving page picks up the guid and translates it back into a querystring.
Purpose is you have a secure way of dealing with info sending via querystrings. Lets say in the past you could easily get other info from the page by just changing a value in the key send via a querystring. In my case lets say the user request a Customer "A" with querystring ?ID=1.
Simple change the query in the addressbar to ?ID=2 (or something else) would give him another customer. Maybe a customer he is not allowed to see. (Of course this can be prevented also in the business layer, but that's not the point.)
So if i simply could create a new QueryStringParameter lets say called QueryStringGuidParameter which i can use in the ObjectDataSource but ideally just for all controllers which are able to use the QueryStringParameter , i don't have to go into code behind and set the SelectParameters in there.

Aug 17, 2010i have a webcontrol that contains a modal popup that allows the user to enter in some information. When the user clicks submit the popup should close and the gridview on the page update. The problem that im currently getting is the page refresh is done before the data is inserted and is currently the last action fired in the life cycle. How can i make the insert within the control the first thing to happen in the page life cycle or update the page gridview once the popup has inserted the information. Im currently placing the datagrid within an update panel with updatemode set to conditional and a trigger on the custom control.
View 1 RepliesWeb Forms :: Dynamic Adding User Controls / Difference Between UserControl And WebControl
Mar 16, 2011I have what is probably a basic question but I do not understand if/why there is a difference. I have a simple asp.net page with a staticly created DropDownList and Panel control. The user can select one of three options if the drop down (Employee, Company, Address) which should load the respective custom UserControl into the panel below. By default, I have the Employee control selected in the drop down and it should be displayed on the intial Page Load (!Page.IsPostBack).
If I do the following it performs the desired behavior on the intial load:
[Code]....
If I try the following, the User Control does not appear on the initial page load:
[Code]....
I noticed if I do it with a textbox instead of a UserControl, it works however:

I assume there is some sort of behavioral difference in the way the loading is done between a UserControl and WebControl.
How To Enable Ajax When Deriving From System.Web.UI.WebControls.WebControl On Controls
Feb 26, 2010I've built a class that derives from System.Web.UI.WebControl. It basically renders pagination links (same as what you see on top of GridView when enabled) for use above a repeater.I'm creating some anchor tags explicitly inside my nav control obviously, but they don't perform ajax postbacks. My understanding is that ajax requires POSTS to work right? Well, these would be GETs

Now that most the user interface is working properly, I'm stuck with the following issue: I want to add a button (html button tag) which has to trigger an event. I have been able to declare the event, the event args, the delegate,etc. The page using my control may assign a handler and that handler is called correctly when I explicitely call OnServerControlClick (The name I gave to the event). I cannot make the link between the button in the user interface and the event in the webcontrol source code. When the button is clicked, I get an error message saying a dangerous Request.Form value has been detected.
