For each control

[Cristiane]

Hi,

I would like ask your help for the following problem...
I have a fom in asp.net (using vb.net) with some buttons. I want enable/disable this buttons using "For each" statement. I tried the following code in the "Page_Load" but it didn't work...

For each Controls as Button in Me.Controls
If Controls.Text = xxxxxx then
controls.Enabled = True
Else
Controls.Enabled = False
End if
Next

Thanks any help

Hi!

The most probable reason that you don't find your buttons is that you only look through the first layer of components. What you need to do is to make a recursive method that goes through all controls and all the controls that is contained in the controls. I myself don't know how to write this in VB since I work with C# but this little function will go through all the controls in your form and look for a specific control. You can easily modify this into what you want it to do.

private bool MyFindControl(Control ctrl, string controlId)
{
bool result = false;

//If the control that has been sent to this method is
//the one we are looking for then return the result.

if (ctrl.ID == controlId)
return true;

//If the control that has been sent to this method is
//NOT the one we are looking for, then go through
//all the controls in the control
foreach (Control control in ctrl.Controls)
{
result = MyFindControl(control, controlId);
if (result)
break;
}
return result;
}

In your Page_Load method you call this procedure like this

bool controlFound = MyFindControl(this, "MyControlId");

I hope this will help you out at least to some degree!

Good luck!

Hi

Use the code below

Dim obj As Object
Dim i As Integer
For Each obj In Controls(1).Controls
If TypeOf obj Is Button Then
If obj.GetType().ToString().IndexOf("Button") > 0 Then
'myBut = CType(myControl, Button)
For i = 0 To 1
If obj.Text = "Button" Then
obj.Enabled = True
Else
obj.Enabled = False
End If
Next
End If
End If
Next

hope it helps
