Hi,
First in the parent window call a javascript function to open a popup window
say
function OpenChildwindow()
{
var retval="";
retval=window.showModalDialog('Userform.aspx','','dialogWidth:400px;dialogHeight:175px;
status:no;dialogHide:true;help:no;scroll:no');
if(retval != "" && retval != null)
{
window.execScript(("__doPostBack('UpdateUser', '" + retval +
"')","JavaScript");
}
}
This opened a modal window and waited for a return value.
I�m calling the __doPostBack() javascript function.
This function will appear in your JS code only when you use certain web
controls, like the LinkButton.
function __doPostBack(eventTarget, eventArgument)
In the Child window
//This function accepts any value of the child form which has to be pass
when calling the function
function ClosePopUp(returnVal)
{
//SET RETURN VALUE OF THE DIALOG BOX OR DIALOG RESULT
window.returnValue=document.getElementById(returnVal).value;
//CLOSE DIALOG WINDOW
window.close();
}
Then in my parent window in the Page_Load() function I did this:
If ( Not Page.IsPostBack )
{
BindGrid()
}
Else
{
If ( Request.Form("__EVENTTARGET") = "UpdateUser" )
{
UpdateItemQuantity(Request.Form("__EVENTARGUMENT"))
}
}
With Request.Form() I could get the values I passed to the javascript
__doPostBack() function and use them in a condition and send them directly
to a asp.net function.
