convert string to object type

Sep 18th, 2009

Hi

I have a procedure that performs checks on controls in my page against rules set in a SQL table. It all works fine except that when im casting the control e.g.

 Help with Code Tags 
 ASP.NET Syntax (Toggle Plain Text) 
 CType(Me.Page.FindControl(control1), TextBox).Text
 CType(Me.Page.FindControl(control1), TextBox).Text

and its a dropdownlist it of course fails.

Im trying to create a variable that gets populated from the table with the correct control type and then use this in the cast. i.e replace textbvox with my variable that could say either 'textbox' or 'dropdownlist'

but if i just put the string value variable in it gives error 'Type 'ControlType' is not defined'.

I wonderd if anyonme had any ideas

Please mark this post as 'Solved' if it has helped and fixed your issue.

Use a condition before casting the control like this:

 Help with Code Tags 
 ASP.NET Syntax (Toggle Plain Text) 
If TypeOf(Me.Page.FindControl(control1)) IS DropDownList Then
    CType(Me.Page.FindControl(control1), DropDownList).SelectedIndex = xyz
End If
If TypeOf(Me.Page.FindControl(control1)) IS DropDownList Then
    CType(Me.Page.FindControl(control1), DropDownList).SelectedIndex = xyz
End If
