variable label control

[Ankit Aneja]

I'm trying to use a for() loop to go through a set of labels and set their
visibility to false.

I had to do something like

Code:

for(int i=1;i<=10;i++)
{
labeli.visible = false;
}

or
for(int i=1;i<=10;i++)
{
String s;
s=("Label"+i);
Label lab=new Label();
lab.ID=s;
lab.Visible=fal se;

}

but i am not getting how to do that pls help

Hi,

Use the page object's controls collection
e.g

int i = 1;
foreach (Control ctl in Page.Controls)
{
if (ctl.name == "label" & i)
{
ctl.visible = false;
}
}

Well, this might not be the cleanest way. But this can be the way to go

Two remarks:
1) the "&" operator is "bitwise AND" in C# (and string-concat in VB).
Use "+" to concatenate strings in C#
2) the Controls collection lists only one level deep. You need to call this
recursively to find "deeper" controls

Thanks Hans for correcting :)
I assumed that the label controls are those put by the user explicitly

Use the ID property. Thats the name with which you identify a control
on server side execution

Hi Ankit,

System.Web.UI.C ontrol only has "ID" property to identify itself, not
"Name". Also, we need to search from the HtmlForm control to loop all the
labels you defined at the top page level( directly under the <form
runat=server>.. .</from> rather than nested in other container controls).
The following code is just a simple example to loop all the top level
labels:

=============== =====
HtmlForm form1 = Page.FindContro l("Form1") as HtmlForm;

foreach(Control ctrl in form1.Controls)
{
if(ctrl is Label)
{
Response.Write( "<br>" + ctrl.ID);
}
}
=============== =====

Hope helps. Thanks,
