Solution 1

Check where you have placed the code for "onclick".
If it is under if(!Page.IsPostBack), move it out of that if condition in Page_Load.

It is outside the page_Load only.

Solution 2

You are adding two eventhandlers to the same event 'onclick'.

One is -onclick="btnedit_Click" in the aspx
Other is - "onclick", "openemppostingjospopup('" + Convert.ToInt32(folderid) + "')"

So remove the onclick event from the aspx page. It will work.

here is the code for edit button

protected void btnedit_Click(object sender, EventArgs e)
{

checkingmultiplevalues();
if (chckcount == 0)
{
lblERROR.Text = "please Select Atleast one folder";
lblerrr.Visible = true;
}
else
{

btnedit.Attributes.Add("onclick", "openemppostingjospopup('" + Convert.ToInt32(folderid) + "')");

}
}

btnedit.Attributes.Add("onclick", "openemppostingjospopup('" + Convert.ToInt32(folderid) + "')");

This line of code should be in Page_Load event and NOT in the click event itself.

Remove all your server side code and add the validation logic in javascript only

Solution 3

write your code :

C#

btnedit.Attributes.Add("onclick", "openemppostingjospopup('" + Convert.ToInt32(folderid) + "')");

inside page load.

it is written in event handler method of button click, thats why your pop up window is opening after post back .
