Trying to pass value to Javascript in a LinkButton

I have a Linkbutton control. When it is clicked I would like to pass a value to a Javascript funcition  to open a pop-up window. Linkbutton and Javascript function are below. I cannot figure out how to pass the studyid (which is basically the text value of the LinkButton) in the OnClientClick=Navigate(???). If I hard code a value it works fine.

Any help would be greatly appreciated.

Jason


function Navigate(StudyID_i) {
            javascript: window.open("TechDetail.aspx?studyid="+ StudyID_i);
        } 

<asp:Linkbutton id="LinkButton1" Text='<%# Eval("StudyID_i") %>' CommandArgument='<%# Eval("StudyID_i")%>'  onclientclick="Navigate(????))" runat="Server" />

try

onclientclick="Navigate(this.value)"

or

 onclientclick="Navigate(this.getAttribute('value'))"

<asp:Linkbutton id="LinkButton1" Text='<%# Eval("StudyID_i") %>' CommandArgument='<%# Eval("StudyID_i")%>'  onclientclick="Navigate(<%# Eval("StudyID_i") %>))" runat="Server" />

Typo graphical error.
Please disregard my post above but instead try the below code:

you need to define it in single quotes else JS will throw an error, something like this

onclientclick="Navigate('<%# Eval('StudyID_i') %>'))"

This should be as simple as:

  onclientclick="Navigate( this.innerText );"

onclientclick="Navigate( this.innerText );"  Seems to be the best solution. At least for me. Thank you all for your help with this.
