The following is predicated on having a web enabled form with code behind ( c# )

Had the need to hide a button control on my web enabled form. I reviewed various articles and posts from the internet and frankly found them (although useful in their own right and I respect the people that volunteered the information)  way too much trouble for my tastes. I figured there just had to be a simpler way to do this,  well for me at any rate. And to my delight I did find a way, only 8 lines of code!...woohoo!

• 1 Textbox
• Some conditional formatting on the button
• 8 lines of code
• 5 minutes of my time without having to mess with Form Data Connections and or other web services etc.

Done!....Wahla 

1)  Placed a textbox on my form. Set the conditional formatting to hide the textbox. Named the textbox   txtHideFlag

(optional )

In the web.config file of the Sharepoint site of where my form resides, I added a Key Value pair variable that would contain the domain user names for people I only wanted to see the button on the form. I did this so I could easily change the names of peoples who were only required to see the button. Rather than hardcoding usernames in the code base, and then having to recompile, re-publish / deploy and so forth.

  Obviously you're going to add the domain users of your domain.

2)  Include System.Configuration to your code base

Using System.Configuration;

 

Then in my forms FormEvents_Loading() function I added the following code....

  

      XPathNavigator root = MainDataSource.CreateNavigator();

string  _securityManagers = "";

 

if (  ConfigurationManager.AppSettings["SecurityManagers"'] != null )

{

       _securityManagers  =  ConfigurationManager.AppSettings["SecurityManagers"']

 

if(  ! _securityManagers.Contains( this.Application.User.UserName ) )

      root.SelectSingleNode("//mytxtHideFlag", NameSpaceManager).SetValue("HIDE");

else

      root.SelectSingleNode("//mytxtHideFlag", NameSpaceManager).SetValue("");

I then configured the button's conditional formatting to hide itself if the mytxtHideFlag textbox = "HIDE".  So the logic / functionality is, if the domain user who is viewing the form in the web browswer, is contained in that list of usernames contained in the Key/Value variable ~( in the web.config) ~, the button will be visible. Otherwise, the button is hidden.
