How do I have it check my variable before allowing a click.
Example :
_StartControl.Click += new EventHandler(StartControl_Click);
I only want them to be able to do that if my variable "isValid" is equal to 1.
I'm not very good at forms.. Have always learned just console apps.
You can check the value of your isValid field inside StartControl_Click method. If the value is 1, you can allow the method to proceed, if it's not 1, you can simply return from the method before anything gets executed.
You can do it like this.
if(isValid==1)
_StartControl.Click += new EventHandler(StartControl_Click);

Will the C# function Convert.ToInt32(text) convert different words to the same int? Any links or pushes in the right direction are appreciated!
P.S.
What about anagrams?
No, Convert.ToInt32(text) will just try to parse your text to an int, like:
Convert.ToInt32("032") will return 32 as int but
Convert.ToInt32("Brian") will throw an exception.
I assume that you want to have some kind of hashing, when you say "different words to the same int".
Try GetHashCode(). It will return the same value if you call it multiple times with the same value, for example:
"Brian".GetHashCode() will always return 1635321435

I want to call every form that exist in the Program/Project,
As i say in the title literally
foreach(Form){
//do somting
}
You can iterate all open forms owned by your application like this:
foreach (Form form in Application.OpenForms){
//do your thing
}
Note: this will only iterate the forms that have instances created.

I've encountered sometimes code like this and I am kind of new to programming. I want to find out what's the meaning behind those objects or data type enclosed in parenthesis.
(int)
(datagridview)
(form)
If you see something like this it's called a cast. It's used to explicitly convert a data type to another data type.
double pi = 3.14159;
int my_int = (int)pi;
See this description on casting for more details.

I want to write some property item to image. Though I could not do it. But I can edit any currently added property. So I want to know is there are any property item I can use for my purpose? Here are some Id I am getting:
Id:271
type 2
Id:272
type:2
Id:274
type:3
Id:282
type:5
Id:283
type:5
Id:296
type:3
Id:306
type:2
....
etc.
My question is can I use any of the currently present property?
Sounds simple i think
<img id="myimage" data-id="data you want to pass"/>
if you want to add attribute from c# then
ddLedger.Attributes.Add('data-id','yourvalue');
So you want to access this property at backend c# then
string aa=myimage.attributes("data-id");
in string aa you will get your data....
and in jquery
$('#myimage').attr('data-id');
Now if you want to add it at run time then like this
$('#myimage').attr('data-id','your id added');

Which method it is called on 3.ToString()?
System.Int16.ToString()
System.Int32.ToString()
System.Int64.ToString()
All integer literals in C# default to int (Int32) unless they are too big for int, in which case they become a larger data type that fits, like long(Int64).
So in this case, Int32.ToString() is called.
System.Int32.ToString() as literal integers are Int32 type
