Hi hismightiness,

CType(source, CustomValidator).ControlToValidate will return ( in string ) the id of the control you want to validate
if you want to search for this control , just type

Page.FindControl (  CType(source, CustomValidator).ControlToValidate )

My quesyion is what parameters to be passed for the function checkValid


Sub checkValid(ByVal s As Object, ByVal e As ServerValidateEventArgs)

end sub

Default checkValid() function  passes the parameters for  Object and ServerValidateEventArgs



if i add new new parameter like

Sub checkValid(ByVal s As Object, ByVal e As ServerValidateEventArgs,Byval controlID as string)

end sub

then

OnServerValidate="checkValid('title')" doest work

@mmarinov ur comment might help but
apart from control ID to validate i have to pass the maximum length for that textbox as parameter.
 which can't be retrieved in function without passing as parameter

DOT_NET,

sorry, but i did not read your question carefully
you can not set a parameter in the way you want, BUT
as i understand your question correclty - you want to use one custom validator to validate more than one controls - correct ?
if yes you have to use

customValidator1.ControlToValidate = "textbox1" and the textbox1 should be put in some conditions
the same conditions that will determine which id you want to pass like in the way you wanted

DOT_NET,

if you want to pass more that on values why you can use sessions
then you don't have to set a specific control to validate

or even better in the button_onclick ( for example ) you can perform your validation manually :)

If you want to use the same server-side function, you'd simply assign the same ServerValidateEventHandler. You DO NOT need a custom implementation for this:

   C#
this.CustomValidator1.ServerValidate += new System.Web.UI.WebControls.ServerValidateEventHandler(this.checkValid);
this.CustomValidator2.ServerValidate += new System.Web.UI.WebControls.ServerValidateEventHandler(this.checkValid);

   VB.NET
AddHandler CustomValidator1.ServerValidate, checkValid
AddHandler CustomValidator2.ServerValidate, checkValid

PS- You'll want to assign the server-side event handlers in the OnInit event handler of the page.
