How insert Data from Textbox at Button_click
|

At first glance there are several things wrong with this code.
1: you create several textbox controls but you don't set there location, so unless 'PH1' is a tablelayoutpanel or flowlayoutpanel all your textbox's will be shown on top off each other.
2: why add a new eventhandler to button1 for every textbox you create.
If button1 is created at designtime you don't need to add an eventhandler to it in code.
If button1 is created at runtime (off which there is no code here) adding it only once should be enough.
3: as to your question, the way you wrote it here you have 2 options.
Having a array variable (global) and adding all your textbox's to this array, then in button click event iterate this array.
Or iterate all the controls in 'PH1', check if there type is of the type textbox and get the text that way.

Can u Post Some code or Links

I knew this question was going to come.
Did you at least try to do anything I said?
I don't write c# so can't help you with that
But here is some vb.net code (easy to convert)
for each c as control in PH1.controls
if c.gettype.equals(gettype(textbox)) then
dim txt as textbox=c
dim textstring as string = txt.text 'now you have the text in the textbox
end if
next

What's the error? please be more descriptive when asking questions.
developer.ravish wrote: How track the Dynamic id of textbox?
What do you mean by this. If you mean how can you just put 'txt1.text' in your code and get the text form that dynamicly created textbox, then you can't (well maybe with reflection but I don't know).

for (int i = 0; i < count; i++)

tr = new TableRow();
tc = new TableCell();
TextBox txtbox = new TextBox();
txtbox.ID = "txt" + i.ToString();
tc.Controls.Add(txtbox);
tr.Cells.Add(tc);
tbl1.Rows.Add(tr);
tr = new TableRow();
tc = new TableCell();
TextBox txt_box = new TextBox();
txtbox.ID = "txt_" + i.ToString();
tc.Controls.Add(txt_box);
tr.Cells.Add(tc);
tbl2.Rows.Add(tr);
}
// tbl1.Rows.Add(tr);
}
}
Now on Button_Click i want to save Data From the Texboxes?

This is completely different than the first code you posted.
But basicly its the same, you'll have to go thru all the rows of tbl1 and tbl2.
Get the cell of that row(since you only have one column you should be able to get it very easy). That cell should then contain your textbox off which you can get the text.
pseudo code (vb.net sorry)
for each row as datarow in tbl1
dim txt as textbox = row.item(0).control(0)
dim data as string = txt.text
next
You'll have to adapt this code it is untested and from memory so...

Create an application that allows the user to enter the length for the three sides of a triangle as ints. The application should then determine whether the triangle is:
• A right triangle, two sides of the triangle form 90-degree angle
• An equilateral triangle, all sides of equal length
• Neither.
You must create a class to represent a triangle object and define the event handler for the Create Button. Define the necessary properties:
Constructor that take the length of the three sides of the triangle as arguments
Three properties that enable clients to access and modify the length of the three sides. If the user enters a negative value that side should be zero.
Tow features to determine whether the sides form a right triangle. The other an equilateral triangle only get accessor "read-only".
help to solve this program..please...please

Obvious homework questions don't go down well here. Be more specific, and show you've had a go first. You might get a useful an answer that way.

Sounds like an extract from an assignment brief lol
is it?
pretty basic stuff really. You know much c#?

Tell you what, as i feel in a helpful mode.
If you post at 12.30pm (My Time (in one hour))saying your still stuck, i will help you out with a bit of code. But give it a try yourself till then. its not too difficult for what you want to do
P.S are you doing a console app or a windows form or what?

Please don't do people's homework for them, not in its entireity anyway. They learn nothing, pass caourses, go out to work and the rest of us spend our life clearing up their mess!

As others have said, you have to do your own homework. If you don't, how do you expect to learn anything?
Provide the code you have written so far along with what you are stuck on and we will be only too glad to help you out.
|
|
|
|
|
Doesn't sound too difficult. What have you got so far and what bits of your code aren't working as expected?

Right - here's how to solve your homework.
You have a good set of requirements there. Are there any areas you are unsure about from the requirements? If yes, seek clarification.
Once you are sure you fully understand the requirements, put a use case together to show how a user would interact with this. For such a trivial problem, the use case will be simple. You may also want to put together an activity diagram to help clarify points.
Now, your thoughts should really be coming together on this, so you are now ready to commit to a design. I'd recommend roughing out a class structure on paper.
Now, follow TDD practices to physically create your application. Remember to test for edge cases - these always end up catching people out.

Hello,
I am creating a windows service which performs 20 operations based on some condition. So at one time one process will be executed.
All these 20 different tasks are separate assemblies added to the windows service. The objects and the call to the assembly will be made only when needed.
For example:
Case "findcustomer"
create object
process
Case "findVendor"
create object
process
Is this approach a good idea? Also I want to know what needs to be keep in mind related to design of this service.
Regards,
Pavas

hi. im thinking of building a multi user game that works over the internet but the clients are a desktop applications.
that means that the application will have to talk to a server on the internet and im not sure about what technology to use when sending messeges between the client and server.
is it "expensive" for example to use web service to communicate with the application?
what is the common use technology when developing such application?
|
|
|
|

Hi,
what do you mean by "expensive"? Regarding the speed of the application or the time to implement the app.
My opinion:
Implementing the app using the low-level TCP/IP (or UDP, depends on the app) protocol will result in fast communication between client and server, because web services are on a much higher level (ISO/OSI) using protocols like HTTP etc. Also you need an IIS to host the service etc. This will all slow down the app. But going this way will need you to invest time, because you have to implement all the stuff like opening sockets, handling server communication etc.
Hope this helps you a bit.
Regards
Sebastian
