If you want to take 10 checkboxes then it is recommended to use checkboxlist, which is relatively simple, and there are two ways to implement you pasted below. One is the value of 10 checkboxes, and the other is the value of checkboxlist, ** as follows, I hope it can help you.
This is to verify multiple checkboxes.
protected void button1_click(object sender, eventargs e)
string content = "";
aa is the name of the container where your checkbox is placed, and I use controlcollection cons = ;
foreach (control con in cons)if (con is checkbox)
checkbox chk = con as checkbox;
if (content += ;
content += ",";
This is the inflammation checkboxlist.
protected void button2_click(object sender, eventargs e)
string content = "";
for (int i = 0; i < i++)if (
content += ;
content += ",";

1. Use the built-in method of C form public control find(string key, bool searchallchildren).
2. Write a foreach loop method foreach (control control in.
3. Direct parent search for child controls; If it is a nested child control, you need to write a recursive method method to get it.
4. Finally, run and choose the search method according to your actual needs.
Notes:
C enables C++ programmers to develop programs efficiently without losing the power of C C++ by calling native functions written by C C++. Because of this inheritance, C is very similar to C C++, and developers who are familiar with similar languages can quickly move to C

control control = "button1", true)[0];
object o = "propertyname").getvalue(control, null);
ev = "click");
You're going to get the event, the second line is to get the property, and the third line is to get the event.
-
Click on the control you need or right-click your control to select Properties, then find the event in the lower right corner of the property, select the one you need in the event, and double-click on the blank space to write. The system adds its own reference to the event in the designer.
-
Use delegates to write a method for your click events.
-
That's it, you have to instantiate it.
-
This first depends on whether the form class where the control is located is instantiated, and if it has been instantiated, it can be done by constructing parameters or delegates.
Constructing parameters: Pass the instantiated object of the form class where the control is located as a parameter to your new form.

c There are hundreds of controls that come with the system, and the total number should be in the 10,000 level with the existing third-party control providers, so it is obviously unrealistic for you to ask about the total number and all the names and attributes.
Controls fall into the following categories:
1.Input control classes: text boxes, checkboxes, etc.
2.Layout control classes: panels, containers, etc.
3.Display Classes: **, graphics, etc.
4.Output class: report, print, etc.
5.Thread control classes: background services, etc.
ps: c is read as c sharp
-
If you don't read the well, it's called sharp
c sharp。
So many things to ask for just 5 points? It's kind of impossible.

I just solved this problem in the morning, I'll show you the **, I don't know if it's what you want.
My xml data is simple :

If you don't know how to speak English, you should know how to choose B.
name is a word in an elementary school English textbook.
-
Select the ba option for the title, c for the style, and d for the appearance.
-
Specify the enable of the control directly according to the user permission setting, what is the use of you to get the control name, and what type of control do you want to get?
Traverse through all control methods:
foreach (control item in
-
Each widget has a name, either you name it or the default name, and you can control whether it is displayed or hidden, available or not.
Just add these label attributes to the timer control.

I think it works, I did it once when I first started working, and I don't remember it very well, but you can try it with the seek function, locate it first, read it later, and I remember when I was doing this, I read the book The C Programmer, which is about 234 pages.
