How to find Controls In Wizard Navigation Steps

Sometimes we need to find a control from Wizard navigation steps. For that we need to use FindControl() method but we fail in this case, as we always get null when using WizardId.FindControl(“ControlId”).
Why?

Because when ASP.NET adds the navigation area controls to the wizard control, it adds a prefix onto the control name.

So to find the control,we need to add the appropriate prefix to the control name, like the following:

Navigation Templates                            Prefix ————————-                  ——————————————- StartNavigationTemplate                     StartNavigationTemplateContainerID$ StepNavigationTemplate                      StepNavigationTemplateContainerID$

FinishNavigationTemplate                   FinishNavigationTemplateContainerID$

Example:

            
   
       
   
            
                    Finish
                
            
            
   
  
  
            

For example, if you want to find a button named “btnTest” in the finish navigation step, you would have to use a line of code.

var testButton= wizTest.FindControl("FinishNavigationTemplateContainerID$btnTest") as Button;
 
if(testButton != null)
{
       testButton.Visible = true; //Show the test button
}
