Introduction
This article shows how to do a Postback with Client Side Object
Using the code
Use of Input Button
Switch to
View-HTML-Code and then inside the
<form> tag add the following
code :-
<input type=button value="Click Me" id="htmlClientButton"
onclick="javascript:doButtonPostBack();"
runat="server" NAME="htmlClientButton">
Add the onclick client event
inside the <head> tag
<script language="javascript">
function doButtonPostBack(){
alert("Welcome to my input button PostBack");
}
</script>
Now we can do the Server code. When we added the runat=server the designer created a server object for us
to use.
Now we just need to attach a method / event for it
this.htmlClientButton.ServerClick +=
new EventHandler(htmlClientButton_ServerClick);
private void htmlClientButton_ServerClick(object sender, EventArgs e)
{
/// do some Server Code
this.Page.Controls.Add(new LiteralControl(''<HR>''));
}
Tablecell PostBack
Do the same as with the button, only
difference
is that you are going to set the style to hidden
<input type=button value="Click Me" id="htmlClientButton"
onclick="javascript:doButtonPostBack();"
runat="server" NAME="htmlClientButton" style="VISIBILITY: hidden">
Attach a Client Side Method Call
<TD onclick="javascript:doTableCellPostBack();"></TD>
Now we need to add the onclick script
inside the <head> tag. Add the following code
<script language="javascript">
function CellPostBack(){
alert("Hello Cell PostBack ");
var theform;
if (window.navigator.appName.toLowerCase().indexOf("netscape") > -1) {
theform = document.forms["Form1"];
}
else {
theform = document.Form1;
}
theform.__EVENTTARGET.value = "MyCellButton";
theform.__EVENTARGUMENT.value = null;
theform.submit();
}
</script>
That's all.
