Looping over my WebControls

[Jim Bancroft]

Hi everyone,

I'm struggling with something.....I'd like to loop over all of my page's
HyperLink controls, and I'm not sure how to do it.

Here's what I'm looking for, in pseudocode:

foreach (System.Web.UI.WebControls.HyperLink hLink in this.Controls)
{

hLink.Target= "fill in value here using custom algorithm";

}

Anyone know of a good way to do this? Thanks very much.

try yhis.....
For Each cntrl As Control In e.Item.Cells(i).Controls
If TypeOf cntrl Is System.Web.UI.WebControls.HyperLink
Then
CType(cntrl, HyperLink).Target= "yahoo.com"
End If
Next

If you are looking to parse all controls on the page then you probably need
to use a recursive function that would scan the child controls of each
control.

I have a sample recursive function on my website that does this;

Yes, the recursive call is the way to go, except that you might want to code
the type checking as

else if ( cntrl is System.Web.UI.Controls.HyperLink )
instead of
else if ( cntrl.GetType().FullName.IndexOf ("HyperLink") !=-1 )

I believe you meant: System.Web.UI.WebControls.HyperLink (instead of
System.Web.UI.Controls.HyperLink). Thanks for the suggestion. I modified
the code sample accordingly.

Yes, I meant System.Web.UI.WebControls.HyperLink. Note that this will not
work if the anchor object <a> is used with (runat=server). In that case,
you'll want to change your if loop to include a type checking for this
object.

If the object is not server side, I believe I saw a client side javascript
example that does the same recursively.
