javascript-window.open

Question

How can I concatenate ID from database and URL?

This is my code. I have an error "The server tag is not well formed."

NavigateUrl="javascript:void(window.open('ChangeHistory.aspx?ID="<%# DataBinder.Eval(Container.DataItem, "id")%>" ','_blank','height=600','width=600') );"

Answer 1

I think this is what you need:

NavigateUrl="javascript:void(window.open('ChangeHistory.aspx?ID=<%# DataBinder.Eval(Container.DataItem, "id")%>','_blank','height=600','width=600') );"

That is, remove the " that was just before <% and the one from just after >% .

Answer 2

You should try adding the NavigateUrl Attribute from server side code...it will be very easy and also to include your ID in window.open method.

if it's in some Grid/Repeater/Datalist then use the DataBound property otherwise use Page_Load event to add attribute to it...

Example

Foocontrol.NavigateUrl=@"javascript:void(window.open
     ('ChangeHistory.aspx? ID='"+YourID+"','_blank','height=600','width=600') )";

Edit

protected void yourGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
  if (e.Row.RowType == DataControlRowType.DataRow)
   {
     HyperLink hlnkViewHistory = (HyperLink)e.Row.FindControl("hlnkViewHistory");
     hlnkViewHistory.NavigateUrl==@"javascript:void(window.open
     ('ChangeHistory.aspx? ID='"+YourID+"','_blank','height=600','width=600') )";
   }
 }

YourID - add your ID whatever you want to send as parameter....

Try this. I have changed this

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# String.Format("ChangeHistory.aspx?id={0}", Eval("id")) %>' onclick="javascript:w= window.open(this.href,'DownloadImage','left=20,top=20,width=500,height=500,toolbar=0,resizable=0');return false;">Open</asp:HyperLink>
