     Some situation user need to trigger the postback dynamically from client side using javascript or jQuery. In this situation you can follow this method. Asp Button <asp:Button ID="dmypbbtn" runat="server" OnClick="dmycall" style="display:none;" /> javascript code document.getElementById("<%=dmypbbtn.ClientID%>").click(); jQuery Code $("#<%=dmypbbtn.ClientID%>").trigger('Click');      When you trigger the click function like the above format, the server side dmycall method will call with serverside postback.

     We can pass the argument to onclick serverside function using CommandArgument attribute like below. Asp Code    <asp:Button id="bid" CommandArgument="456" runat="server" OnClick="passvalue" /> serverside code (.cs)     protected void passvalue(object sender, EventArgs e)     {         LinkButton btn = (LinkButton)(sender);         String testval = btn.CommandArgument; //Returns 456     }

     We can pass the arguments(values) to onclick serverside function using CommandArgument attribute. Here we send the value using the same way of single value passing, but every values are separated by comma and from serverside we can split into unique data value. Asp Button    <asp:Button id="bid" CommandArgument="456,Rajesh" runat="server" OnClick="passvalue" /> serverside code (.cs)     protected void passvalues(object sender, EventArgs e)     {         LinkButton btn = (LinkButton)(sender);         String fullvalue = btn.CommandArgument;   //"456,Rajesh"         String[] args= fullvalue.Split(new char[] { ',' });         int mark = Convert.ToInt32(args[0]);   //Returns 456         string name = args[1];   ...
