        var ddlbus=document.getElementById(ddlb);<br />
        var ddl=document.getElementById(rpType);<br />
        alert(ddlbus.id);<br />
        if (ddl.value==1)<br />
        {<br />
            alert('false');<br />
            return false;<br />
            }<br />
        else <br />
        {<br />
            alert('true');<br />
            return true;<br />

All alerts are correct in both cases. But even when returning true it is not posting back. On design i set Autopostback =true.

That's the problem make Drop down auto post back true initially
Check the attribute of the drop down Autopostback it should be true
There is no meaning in making auto post back true at server side
As it will not go to server

I did.
Check the attribute of the drop down Autopostback it should be true
It is true.
There is no meaning in making auto post back true at server side
I didnt get you!!!!

Thanks

Any other idea..

Hi,

I think the code which you written wont work fine because you are using single quote(') while passing control id.

The actual code should be like....

ddlBusinessLinesL1.Attributes.Add("onchange", "javascript:return DisableBLPostBack(" & ddlBusinessLinesL1.ClientID & "," & ddlReportType.ClientID & ")")

Thanks for your reply, but actually there is nothing wrong with the code. It is returning the alert, but what i need is to make it post back when alert = true.

The Good way:

1) Check if Session["id"] is not null.
2) Use Session["id"].GetType() to identify the name and whether it is castable to a DataSet.
3) Then do a cast.

Hi,

The below code works fine.The problem in your code is you are converting the session value into String and then casting to dataset so it is giving problem.
Actually ypu need to convert the session value directly to dataset.

Example:-

DataSet ds1;
ds1 =(DataSet)Session["id"];

Sandeep Akhare18-Jul-07 23:13

But the question is What is the logic converting a Session Variable into Dataset ? Poke tongue | ;-P

The logic for converting the session to dataset is just by doing explicit type casting directly.
