Hi There,

I am wanting to call a javascript function from inside a hyperlink control, the function works fine Its just not working when I try to put the value of a       Container.DataItem inside it. Is it legal to do this? I guess I'm probably missing a comma or something.

Sean - thanks in advance                  

<asp:HyperLink runat="server" Text="<%# DataBinder.Eval(Container.DataItem, &quot;shopname&quot;)%>" NavigateUrl="javascript:RefreshParent('<%# DataBinder.Eval(Container.DataItem, &quot;shop&quot;)%>');" ID="Hyperlink1"/>

follow this:

<a class="partname" href="partdetail.aspx" onclick="hideQstring('pt_recno', '<%# DataBinder.Eval(Container.DataItem, "pt_recno") %>')" target="_blank"><%# DataBinder.Eval(Container.DataItem, "pt_shortdesc") %></a>

and:

<IMG SRC="<%# findImage(Convert.ToInt32(DataBinder.Eval(Container.DataItem, "pt_recno"))) %>" align="absMiddle" border="0"/>

try these two:

1.
<asp:HyperLink runat="server" Text="<%# DataBinder.Eval(Container.DataItem, 'shopname')%>" onClick="javascript:RefreshParent('<%# DataBinder.Eval(Container.DataItem, "shop")%>')" ID="Hyperlink1"/>

2.
<a onClick="RefreshParent('<%# DataBinder.Eval(Container.DataItem, "shop")%>')">
<%# DataBinder.Eval(Container.DataItem, 'shopname')%>
</a>

"Is it legal to do this?"

Yes.

As mentioned, &quot; should instead be a " (quotation mark).

Also, I've had problems before using double instead of single quotes for elements when binding (hopefully Microsoft has the problem fixed by now) so if you're still getting a funky error try changing:

Text="<%# ... %>"

  -to-

Text='<%# ... %>'

In your databinding for the text property of the hyperlink, you are binding to "shopname" and then for your js call, you are binding to "shop".  Is this right?  Should "shop" be "shopname"?

Also, an option would be to have the column with the "shop" value you want to pass to RefreshParent() as a column in your grid (I am assuming that is your container?) that is marked as not visible.  Let's say that is column index #1.  You could use the ItemDataBound event and code like this:

if (e.Item.ItemType != ListItemType.Header && e.Item.ItemType != ListItemType.Footer)
{
     // resolve hyper link.  assuming it is in colunm index 2.  make sure you give your hyperlink control an id string (i'll use "hyperlinkName").
     HyperLink link = (HyperLink)e.Item.Cells[2].FindControl("hyperlinkName");

     // set NavigateUrl
     string shop = e.Item.Cells[1].Text;
     link.NavigateUrl = "javascript:RefreshParent('" + shop + "');";
}
