Sorry, i forgot to tell u I am coding in vb.net .
i am having java script code for creating popup calendar which i am calling in html page as shown below.

</asp:textbox><IMG id="Img1" style="WIDTH: 24px; HEIGHT: 21px" onclick="NewCal('txtDate','mmddyyyy',false,24);"
height="21" alt="Pick a date" src="../icons/date.ico" width="24" align="absMiddle" border="0" runat="server">

Now i want to reuse the same javascript code for On click of Image icon which is generated Dynamically in code behind of vb.net

this is what i have tried to do with java script in code behind of vb.net

ibg.Attributes.Add("onClick", "javascript:return newcal(txtedate1, mddyyyy, False, 24)")

this is the javascript function i am goin to call
where [B]ibg[/B] ---> is the image button ID.
txtedate1 --> is the textbox ID for which i have to specify the date.

hi yashaswi,

You can try out in this way
[CODE]
Protected Sub GridView1_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowCreated

Dim gr As GridViewRow

For Each gr In GridView1.Rows
gr.Cells(0).Attributes.Add("onclick", "window.open('ConDet.aspx?id=" & gr.Cells(0).Text & "','popWin','width=600px,height=380px');")

Next gr

End Sub
[/CODE]

Instead of extra calender image you can use ,Image inside Textbox using css it is very easy .........Try below code:
.TextBoxDateWaterMarked
{
background-image:url(images/calendar_icon.gif);
background-position:right;
background-repeat:no-repeat;
height: 16px;
width: 140px;
padding: 2px 2 2 2px;
border: 1px solid #BEBEBE;
background-color: #F0F8FF;
color: Gray;
font-weight:bold;
font-size: 10pt;
text-align: left;
}
