Loop through the labels of a page to assign text - asp.net

Question

I have some 20 labels on my aspx page for which the IDs are lbl1,lbl2....lbl20 and text is driven by SqlServer table. Is there any easy way to loop through all the labels on the page and assing the text from reader.
I did some thing like but it doesn't work.
SqlDataReader Reader = new SqlDataReader();
int i = 0;
while(Reader.read())
{
label lbl = new label();
lbl.ID = "label" + i;
lbl.text = Reader["ColumnName"].ToString();
}
Is there any other method through which I can loop through all the labels and assign text for it?

Answer 1

If you have them in a container, i think you can do something like this below:
For Each lbl As Control In Grid1.Children
If TypeOf lbl Is Label Then
'your logic
End If
Next
I have only tried this in silverlight however, so i'm not sure it works, or if putting them all in a container is practical in your case.

One way to do this is use the findcontrol method. This would work well because all your labels are named with a "lbl0", "lbl1"... convention.
**start looping:
int index = 0;
string currentLabel = "lbl" + index.ToString();
index++;
Control myControl1 = FindControl(currentLabel);
// cast control to type: (label)
// apply text from reader**
Give that a shot. Hope it works out

I have used this in the past and I just tested it out.
You can do this because every page has a form
HtmlForm form1 = (HtmlForm)Page.FindControl("ContentPlaceHolder1");
for (int i = 1; i <= 3; i++) {
((TextBox)form1.FindControl("label" + i)).Text = "This is label number " + i;
}
If you have a master page change the first line to this
ContentPlaceHolder ph = (ContentPlaceHolder)Page.FindControl("ContentPlaceHolder1");
