Question

Is it possible to raise “onclientclick” event automatically with program.

<asp:LinkButton ID="lnk" runat="server" OnClientClick="javascript:show();return false;" Text="here"></asp:LinkButton>

Here i need to call show() function in some areas of program. I know to call using Page.ClientScript.RegisterStartupScript. But i dont want to use that. Is there any possibility?

Thank you

you can try like this

  <asp:linkbutton id="LinkButton1"
           text="Open Web site"
           onclientclick="Show()"
           onclick="LinkButton1_Click"
           runat="Server" />

and javasript like this.

<script type="text/javascript">
          function Show()
          {
            alert('messagebox');
          }    

        </script>

if you want to return some thing from your javascript, you can try like this.

OnClientClick="JavaScript: return ReturnSomething();"

javascript with return values

<script type="text/javascript">
     function ReturnSomething()
    { 
      if(notvalid)
      { 
         return false; // returning false will cancel postback
       }
      else
         return true; 
    }

    </script>

Edited : you can add like this. in your code file.

lnkbutton.Attributes.Add("onclientclick", "javascript:return Show();");
