The following is an example I use in my apps:

<SCRIPT language="javascript" type="text/javascript">
<!--
      function openPopUp(url){
            window.openurl, "","height=500,width=700,status=yes,toolbar=no,menubar=no,location=no,resizeable=no,scrollbars=yes");

}

-->
</SCRIPT>

<a href="#" onclick='<%# "openPopUp(moredetails.aspx?p=" & Trim(DataBinder.Eval(Container.DataItem, "proposal")) & "&phase="  Trim(DataBinder.Eval(Container.DataItem, "sort_code")) & ")" %>'>


      

 

by: thirdPosted on 2007-06-25 at 07:46:22ID: 19356030

if you only need to open this on a new browser, add the target attribute

<td><a href='moredetails.aspx?p=<%#Trim(DataBinder.Eval(Container.DataItem, "proposal"))%>&phase=<%#Trim(DataBinder.Eval(Container.DataItem, "sort_code"))%>' target="_new">

 

by: thirdPosted on 2007-06-25 at 07:48:26ID: 19356052

slight fix to culshaja's code. missed the open parenthesis

window.open(url, "","height=500,width=700,status=yes,toolbar=no,menubar=no,location=no,resizeable=no,scrollbars=yes");


and the 'return false after calling the function to prevent the href from executing.

<a href="#" onclick='<%# "openPopUp(moredetails.aspx?p=" & Trim(DataBinder.Eval(Container.DataItem, "proposal")) & "&phase="  Trim(DataBinder.Eval(Container.DataItem, "sort_code")) & ")" %>;return false;'>

 

by: culshajaPosted on 2007-06-25 at 07:48:38ID: 19356053

Just remember that the target attribute opens a full browser, whereas using script you can control the size a functionality of the opened browser.

I tried both of your codes and returned me the errors. Below is what I have. BTW, I add the javascript  openPopUp function in the header already.

The errors are:
Comma, ')', or a valid expression continuation expected.
Overload resolution failed becasue no accessible 'ToString' accepts this number of arguments.
End of statement expected.

 <itemtemplate>
      <tr>
         <td><a href="#" onclick='<%# "openPopUp(moredetails.aspx?p=" & Trim(DataBinder.Eval(Container.DataItem, "proposal")) & "&phase="  Trim(DataBinder.Eval(Container.DataItem, "sort_code")) & ")" %>;return false;'>
         
          <div align=left><%#Trim(DataBinder.Eval(Container.DataItem, "proposal"))%>/<%#Trim(DataBinder.Eval(Container.DataItem, "sort_code"))%></a></td>

 

by: culshajaPosted on 2007-06-25 at 08:32:28ID: 19356492

It should be:

onclick='<%# "openPopUp('moredetails.aspx?p=" & Trim(DataBinder.Eval(Container.DataItem, "proposal")) & "&phase="  & Trim(DataBinder.Eval(Container.DataItem, "sort_code")) & "')" %>'

Should I get rid of -> a href="#" ?
Thanks.

 

by: mrongPosted on 2007-06-25 at 08:45:14ID: 19356625

The code got compiled, but when I ran it, it gave me syntex error and no popup window show up.
Thanks.

What does the A look like in the html source of the page when its in the browser?

james :-)

 

by: mrongPosted on 2007-06-25 at 09:06:12ID: 19356828

When I put my nouse cursor over the link, it shows the following:

https://.../report.aspx?shop=BL#

https://.../report.aspx?shop=BL is the orginial page.

Thanks.

 

by: culshajaPosted on 2007-06-25 at 09:12:44ID: 19356874

I would replace the A with a SPAN that you can then apply the correctstyles to, to make it look like an A. You can then still assign an onClick attribute in the same way.

The following is another example of how I do things:

In the ASPX page:

<SPAN CLASS="fakeLink" ONCLICK='<%# CreateReadMailScript(DataBinder.Eval(Container, "DataItem.message_id"))%>'>Read</SPAN>

In the ASPX.vb page:

Public Function CreateReadMailScript(ByVal messageId As Integer) As String

        Dim script As New System.Text.StringBuilder

        script.Append("window.open(""../messaging/viewmail.aspx?id=")
        script.Append(messageId)
        script.Append("&token=")
        script.Append(HttpUtility.UrlEncode(token))
        script.Append(""", """",""height=500,width=790,status=yes,toolbar=no,menubar=no,location=no,resizeable=no,scrollbars=yes"");")

        Return script.ToString

    End Function

This might be a better way for you.

Well. What is wrong with the code below? I think it is much simple and I don't need to worry about passing any parameters.

<td><a href="#" onclick='<%# "openPopUp(moredetails.aspx?p=" & Trim(DataBinder.Eval(Container.DataItem, "proposal")) & "&phase="  Trim(DataBinder.Eval(Container.DataItem, "sort_code")) & ")" %>;return false;'>

Thanks.

 

by: thirdPosted on 2007-06-25 at 16:53:57ID: 19360137

i see that you're parameter is not passed as string. you need to put quote within it. not a c# expert but try this

<td><a href="#" onclick='<%# "openPopUp(""moredetails.aspx?p=" & Trim(DataBinder.Eval(Container.DataItem, "proposal")) & "&phase="  Trim(DataBinder.Eval(Container.DataItem, "sort_code")) & """)" %>;return false;'>

 

by: culshajaPosted on 2007-06-25 at 23:59:28ID: 19361376

Yep, that should fix it.

Below is what I have but still got same errors as before :(

<td><a href="#" onclick='<%# "openPopUp(""moredetails.aspx?p=" & Trim(DataBinder.Eval(Container.DataItem, "proposal")) & "&phase="  Trim(DataBinder.Eval(Container.DataItem, "sort_code")) & """)" %>;return false;'>
          <div align=left><%#Trim(DataBinder.Eval(Container.DataItem, "proposal"))%>/<%#Trim(DataBinder.Eval(Container.DataItem, "sort_code"))%></a></td>

 

by: thirdPosted on 2007-06-26 at 06:45:07ID: 19363564

there a missing '&' after the "&phase=". if that doesn't work yet, please post the generated code on this portion.

<td><a href="#" onclick='<%# "openPopUp(""moredetails.aspx?p=" & Trim(DataBinder.Eval(Container.DataItem, "proposal")) & "&phase="  & Trim(DataBinder.Eval(Container.DataItem, "sort_code")) & """)" %>;return false;'>
          <%#Trim(DataBinder.Eval(Container.DataItem, "proposal"))%>/<%#Trim(DataBinder.Eval(Container.DataItem, "sort_code"))%></a></td>

i have used popup Window on DataGrid like this.

protected void dgSubProject_ItemDataBound(object sender,DataGridItemEventArgs e)
{
if(e.Item.ItemType==ListItemType.Item || e.Item.ItemType==ListItemType.AlternatingItem)
{
       HyperLink  hStartDate=(HyperLink)e.Item.FindControl("EmpID");
      hStartDate.Attributes.Add("onClick","popWindow(' " + dgSubProject,DataKey(e.item.itemIndex) + "');");
   
}
}

Add a function popWindow in .aspx page

<script language="javascript">
function popWindow(EmpID)
{
launchCenter("EmpDetailsaspx?comefrom=differentPlace&EmpID="+EmpID, "content1", 480,860);
}

function launchCenter(url, name, height, width) {
                  var str = "height=" + height + ",innerHeight=" + height;
                  str += ",width=" + width + ",innerWidth=" + width;
                  if (window.screen) {
                        var ah = screen.availHeight - 30;
                        var aw = screen.availWidth - 10;

                        var xc = (aw - width) / 2;
                        var yc = (ah - height) / 2;

                        str += ",left=" + xc + ",screenX=" + xc + ", scrollbars = yes ";
                        str += ",top=" + yc + ",screenY=" + yc + ", scrollbars = yes ";
                  }
                  return window.open(url, "popwindow", str);
            }


</script>

it works perfectly on my app
