Suppsoe that a certain dynamic property of a ViewBag object is optional. How can I check whether it has been created or not?
My first reaction is to check for null value.
Code:
@if (ViewBag.OptProp != null) {...}
But then how to handle the case when the property has been actually created, but the value assigned to it is null ?
How do I check if an object has a property in JavaScript?. Except mine is about .NET .
I am trying to figure out how to get the text value from each textbox on a page that has a dynamically created number of text boxes. I need to store that value in a database row. I guess what i need is to be able to store the text box values in a collection or arrary of some sort and then be able to use textbox(i).value or something of that nature. Not really sure where to begin.
View 5 Repliesmy web application i use FindControl to retrieve a Control By Name (it returns an System.Web.UI object). The control can be of various type and I don't want to treat them differently: I'd like to set the Text property to a defined string. I hope there's a class that I may use to cast the control and set the Text property.

I have build a composite control which renders a TextControl or a RADEditor control, dependable of a property a set. Both rendered controls have a Text-property. The problem is that when I change the Textvalue on my webpage (when it is running) it won't set the new Text-value but the old Textvalue instead.

I'm writing a program that inserts controls onto a webform dynamically. Depending on a variable, I add either a textbox, a set of radio buttons, or a set of checkboxes. Later, after a user clicks a submit button I need to use the controls to determine if the user is submitting the correct answer, but when I try to reference the id of a control, I get "txtAnser is not declared. It may be inaccessible due to it's protections level.

View 2 RepliesI'm creating a static helper class for web services I'm writing. I'm tapping into the API of Telligent and therefore creating these Telligent "service" objects that allow me to do things with the platform. For example, I'm creating a MembershipSerice object in my helper class so I can do membership stuff with the same object. In my helper class I have a property with a getter that creates a new one of these objects:
private static MembershipService _MembershipService {
get return new MembershipService(path, usr, pwd);

Just for practice purpose I have created one class called MathFunctions like below:
namespaceCSHWEB
{
public
class
MathFunctions
{
public
double
SimpleInterest(double
PrinicipalAmount, double
TimePeriod, double RateOfInterest)
{
return
(PrinicipalAmount * TimePeriod * RateOfInterest) / 100.0;
}
}
}
Now,
how can I invoke above method SimpleInterest with its parameters without instantiating the class?
Im trying to dynamically create a popup control extender for labels which are also dynamically created. the labels are one a dynamically created accordion pane. Here is a section of my Page_Init method:
[Code]....
When I run the site with this code I get the following error:Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors.Parameter name: element
I thought it might be because the target control ID changes during compilation so i tried to find the labels in the Page_InitComplete method with this:[Code]....
The expression in the FindControl argument is what the id of the label looks like when i view source in my browser after running the page.I also tried to use the popup control's DynamicControlID property, but im not sure what the DynamicServiceMethod is for.

I have created some imagebuttons dyanmically on page_Init. But the above code always returns null. Why is that? How can I check If an image button has posted back?
Note: I am able to handle the click events of those imagebuttons.
I've a JavaScript function in my page through which i make some elements in the page as 'JQuery UI droppable'.
function setDroppableTargets()
{
$(.cssDockZone).droppable();
}
But the elements with the class cssDockZone is created dynamically upon user interaction. So in the code behind i create the control first and finally at the end i register a scriptblock which calls setDroppableTargets().
//set droppable targets ClientScript.RegisterClientScriptBlock(this.GetType(), "setDroppableTargets", "setDroppableTargets()", true);
But the javascript function is invoked before the controls are created eventhough i register the script at the end (after creating the controls) and i cross checked it by getting the elements with class name '.cssDockZone' and i getting it as 0.
$(.cssDockZone).length
I'm creating some linkbuttons dynamically and assigning properties like below. Also I'm adding an event handler to the created link button:
[Code]....
What happens here is when the links created at runtime are clicked, most of the links are linked to other applications. (e.g from app1 to app2, app1 to app3 etc..) So when moving from the current app to the next I want to abandon the current session. However, this event is not firing before navigating to the next page. Could someone suggest a workaraound or the correct way to accomplish that?
I've created a bunch of asp:hiddenfields dynamically at runtime in an asp.net page.
My question is this:
