At the time of compiling, It gives an 2 error.
The error is as follows:


[B]The name 'txtstartDate' does not exist in the current context[/B]	C:\\Inetpub\\wwwroot\\LicenseSoftware\\UI\\LicenseSoftware\\softwareMaster.aspx	366	
[B]The name 'txtEndDate' does not exist in the current context[/B]	C:\\Inetpub\\wwwroot\\LicenseSoftware\\UI\\LicenseSoftware\\softwareMaster.aspx	377

Please Help me.

The only time you can access the clientid of an item in a template is in the itemdatabound event as far as I know. Are you looking for the clientid so you can access it through script? If so I personally would prefer to use unobtrusive javascript and give my controls class values that I can search for.

Not quite–there are alot of ways to skin that cat. The key thing to remember is that your template controls exist on a per-row basis, so you need to call FindControl() from the correct NamingContainer. I really can’t advise much more because I am still unclear on what you are actually doing here–why do you need the ClientID and what are you using it for?

Yeah forgot you can also drill right in through the gridview:-

gridview1.Rows(x).FindControl(“mycontrol”)

I am looking a client ID beacuse i want to pass it to a Javascript calender Function which will return the clickable date to that textbox ID .

Any Way i have solved it…

and i am posting it how i am solved it…
Javascript Code


 function mfCalender(parametrId,position)
    {
    var tblobj=document.getElementById("<&#37;=gvSoftwareMaster.ClientID%>");
    var strClientId="";
     for(var i=1;i<tblobj.rows.length;i++)
          {
            if(tblobj.rows[i].cells[position] && tblobj.rows[i].cells[position].childNodes[0] && tblobj.rows[i].cells[position].childNodes[0].nodeName == 'INPUT' && tblobj.rows[i].cells[position].childNodes[0].type == 'text')
                {
                strClientId=tblobj.rows[i].cells[position].childNodes[0].id;
                   if(strClientId.indexOf(parametrId)>0)
                    {
                    show_calendar(strClientId);
                    }
                }
           }

    }

Aspx Grid View Code

                    </Columns>
                </asp:GridView>

The problem is solved. I asked another function and from that i call it calender function.
