I have ac# method which stores data to sql server. This function is called from an Onlick and i pass the parametres using CommandArgument. Like this.
<asp:LinkButton runat="server" onClick="save" CommandArgument='<%# Eval("post_id").ToString() + "," + Eval("user_id").ToString()%>'></asp:LinkButton>
This is the c# method
protected void vote(object sender, EventArgs e)
{
LinkButton lb = (LinkButton)sender;
string arguments = lb.CommandArgument;
string[] args = arguments.Split(',');
string post = args[0];
string user = args[1];
.............
}
All i want to do is to call the c# method using ajax because i dont want the page to be refreshed, but i cant call that function passing CommandArgument. I want to use CommandArgument because i dont want the c# method to have other parametres than object sender and EventArgs e
Try this:
<asp:LinkButton runat="server" onClick="save" CommandArgument='<%# Eval("post_id").ToString() + "," + Eval("user_id").ToString()%>'></asp:LinkButton>
In script
tag:
$("#<%= myVote.ClientID %>").click();
Attempt 2:
In script
tag:
var func = $("#<%= myVote.ClientID %>").attr('OnClick');
eval(func);
The idea is that Asp.Net WebForms uses JS to do postback to backend, a function generated called __doPostBack
, the idea is to use the same function and call it, or just inspect the generated HTML of the page and get the value of ,as I remember, OnClick
attribute of the button, and use it.
