Question

0.00/5 (No votes)

See more:

"I need something like that"

string obj= something;
this.obj.Visible = false;

Not

this.Controls[SomeButtonName].Visible = false;

"Or tell me the way to execute this code from the string"

string command = "this.something.visible=false";
execute(command);

Thanks very much.

You might want to check on the devexpress forums and blogs.
They have some more information about this.

"I need something like that"

string ctrlname = btn1;
this.ctrlname.Visible = false;

Why you would ever want to use code like that is not something I understand, but it can be done:

C#

string SomeButtonName = "button1";
this.Controls[SomeButtonName].Visible = false;

"Or tell me the way to execute this code from the string"

string command = "this.btn1.visible=false";
execute(command);

This, a question of deferred compilation and execution of a string as C# code, is a much deeper question: you will find, if you search CP, several excellent resources on executing at run-time code in a string.

I am completely unclear how these two questions relate to the overall issue of permissions raised by your question.

But, hope this helps !

Thanks BillWoodruff. I've searched many times in CP, and many other forums, and found several excellent resources on executing at run-time code in a string.
But still cannot use
<pre>string command = "this.btn1.visible=false";
execute(command);</pre>
...

I've found many resources and example. They work well for math and messagebox.show().
But not for my need.

Please help me

<pre lang="cs">string command = "this.btn1.visible=false";
execute(command);</pre>
