I'm not sure what you try to achieve.
A Label raises an Event "TextChanged".
What is your Problem ?

Member 11922776 27-Oct-15 7:47am

label arise label_Click event when double click on label. I want label textchange event instead.

Ralf Meier 27-Oct-15 7:56am

This happens by working with the Visual Studio Editor.
The Click-Event is automaticly selected. But you could also change this to the TextChanged-Event. Take a look to my Solution ...

I'd rather use the readonly textbox that look like a label.

Why ?

BillWoodruff 27-Oct-15 11:59am

Is the Label you wish to invoke a TextChanged Even on the same Form where you want to receive (subscribe to) the Event.

In other words is it the case that when a Label on a second Form has its text changed, you want to raise an event that is defined on another Form ?

There is no such event is asp.net but you can achieve similar functionality using JQuery.
Check these links for further information-

Suvendu Shekhar Giri 27-Oct-15 7:53am

Suvendu Shekhar Giri 27-Oct-15 7:54am

Member 11922776 27-Oct-15 7:57am

Ok,Sorry for that. Is there any solution for this?

Solution 2

Labels don't have text changed events, because they can't receive the keyboard focus, so all changes must be down to your own code rather than user actions.

If you need a change event as a result of your code actions, then consider using a read-only TextBox instead.

Is not possible with label?

Ralf Meier 27-Oct-15 7:53am

@OG:
Sorry but I must correct you :
Label derives from Control and it has a TextChanged-Event - why not ...?

OK ... I think like you.
That helps EVERYtime.

Solution 3

Try it like this :

C#

private void Label3_TextChanged(System.Object sender, System.EventArgs e)
{
    Button3.Text += "-";
}

private void Button3_Click(System.Object sender, System.EventArgs e)
{
    Label3.Text += "x";
}

Its not working

Ralf Meier 27-Oct-15 8:09am

Have you connected the right eventhandlers to the both methods ? Perhaps you do it in the Designer on the Propertygrid of both Controls.

Ralf Meier 27-Oct-15 9:03am

What about your Problem now ?
Is it working like you want ?
If Yes : please accept my answer formally ...
If No : give more Information ...

BillWoodruff 27-Oct-15 11:40am

imho, asking the OP to accept your answer is not a good idea.

Ralf Meier 28-Oct-15 5:40am

Perhaps you are right ...
But to get a Feedback from the Inquirer when he has written, that the Suggestion is not working, would be nice ...

Member 11922776 28-Oct-15 8:48am

I don't want to use two event handlers,thats why it is better choice to go for textboxchanged event. sorry for late reply.

Ralf Meier 28-Oct-15 10:05am

You don't Need 2 Eventhandlers - you only need the Eventhandler from the Label. My Code-Snippet is only to show what happens.
The Button-Click changes the Text from the Label. Then the TextChanged-Event from the Label changes the Text from the Button (to see a response).
But I must say that I now not more understand what you try to achieve - sorry.

Solution 4

Considering the only way to change the test of a Label is through your code, why are you even trying to use the TextChanged event? If your code is changing the text, just call the frickin' method that you want to put in the TextChanged event handler after changing the text of the Label!

Dave, I think it's possible (though, perhaps unlikely) that some other code object could have a reference to the Label, and change its text.

Dave Kreskowiak 27-Oct-15 14:19pm

Possible, but not exactly a good method of communication between two pieces of code that handle data. Events on UI controls are meant to be used to control the UI, nothing more.
