Hi everyone,

I've been trying to pass a parameter to my popup window but I still can't do it. I think that I am close because a browser

window opens but it's a "Page cannot be found" page.

Can you tell me what I'm doing wrong? Do I need the javascript function and the inline javascript? Here's my code:

I started with the <head> tag

function openPopup()

{

window.open("largerImage.aspx","title", "Height=300px, Width=300px");

}
</script>

</head>

______________________________________________________________

Here's my Hyperlink. The part I'm having problums with is the NavagateUrl attribute.

<asp:HyperLink ImageUrl = '<%# "../images/" + DataBinder.Eval(Container.DataItem, "ImagePath") %>' runat="server"

NavigateUrl='<%# javascript:var openPopup = window.open("largerImage.aspx?Param1="& DataBinder.Eval

(Container.DataItem,"Name")%>> ' ID="Hyperlink1"></asp:HyperLink>

Why won't my popup window show? Thanks for any help with this one.

Because your code is not right. In your code, you are not taking any parameters for the openPopup method, but here you are "trying" to pass the lasrgerImage.aspx?param1......

So, from my understanding your code should be as follows

function openPopup(var url)

{

window.open(url, "title", "Height=300px, Width=300px");

}
</script>

<asp:HyperLink ImageUrl = '<%# "../images/" + DataBinder.Eval(Container.DataItem, "ImagePath") %>' runat="server"

NavigateUrl='<%# javascript: openPopup ("largerImage.aspx?Param1="& DataBinder.Eval(Container.DataItem,"Name") &")" %>> ' ID="Hyperlink1"></asp:HyperLink>

Hi Kumar, you code seem very logical but I am getting the error message that states: "The server tag is not well formed". I've tried moving the quotation marks around but no change. Here's a copy of it:

<asp:HyperLink ImageUrl = '<%# "../images/" + DataBinder.Eval(Container.DataItem, "ImagePath") %>' runat="server" NavigateUrl='<%#javascript:openPopup("largerImage.aspx?Pram1="&DataBinder.Eval(Container.DataItem, "Name")&")"%>>'ID="Hyperlink1">
</asp:HyperLink>

The NavigateUrl attribute has a problem but I can't figure it out. Thanks for helping me with this one.

You have the databinding hash at the wrong place. It should be as follows

<asp:HyperLink ImageUrl = ' "../images/ + <%#DataBinder.Eval(Container.DataItem, "ImagePath") %>' runat="server" NavigateUrl='javascript:openPopup("largerImage.aspx?Pram1="&<%#DataBinder.Eval(Container.DataItem, "Name")&")"%>>'ID="Hyperlink1">

try this

<asp:HyperLink ImageUrl = '../images/<%#DataBinder.Eval(Container.DataItem, "ImagePath") %>' runat="server"

NavigateUrl='javascript:openPopup("largerImage.aspx?Pram1=<%#DataBinder.Eval(Container.DataItem, "Name")%> ")'ID="Hyperlink1" ></asp:HyperLink>

Hi Kumar, thanks for helping me with this. Unfortunately I’m still having the tag not well formed error.

Here’s a link that works. This is before I tried to send parameters to the script:

<asp:HyperLink ImageUrl = '<%# "../images/" + DataBinder.Eval(Container.DataItem, "ImagePath") %>' runat="server" NavigateUrl="javascript:openPopup();" ID="Hyperlink1"></asp:HyperLink>

This is my latest try:

sp:HyperLink ImageUrl = '<%# "../images/ + <%#DataBinder.Eval(Container.DataItem, "ImagePath") %>' runat="server" NavigateUrl='javascript:openPopup("largerImage.aspx?Pram1=<%#DataBinder.Eval(Container.DataItem, "Name")%>")'ID="Hyperlink1">

</asp:HyperLink>

It looks like it should work but I can’t seem to find the right placements for the quots.

Please use the following. You have some single and double quote issues.. The following should clear them up

<asp:HyperLink ImageUrl = '../images/ <%#DataBinder.Eval(Container.DataItem, "ImagePath") %>' NavigateUrl='javascript:openPopup("largerImage.aspx?Pram1=<%#DataBinder.Eval(Container.DataItem, \"Name\") %> ")' runat="server" ID="Hyperlink1"> </asp:HyperLink>

Try:

<asp:HyperLink ImageUrl = '../images/ <%#DataBinder.Eval(Container.DataItem, "ImagePath") %>' NavigateUrl="javascript:openPopup('largerImage.aspx?Pram1=<%#DataBinder.Eval(Container.DataItem, \"Name\") %> ')" runat="server" ID="Hyperlink1"> </asp:HyperLink>

If you have access to the param u want to pass in the .aspx.cs file, u can set the NavigateUrl property of the hyperlink there

Hyperlink1.NavigateUrl = "";

Hi the page loads with errors and the hyperlink images aren’t showing. I suspect it’s this portion of the hyperlink:

'../images/ <%#DataBinder.Eval()

When I changed the front end of the tag to look like this:

'<%# "../images/" + DataBinder.Eval()

the images loaded but still with the error on page message.

I suspect your images does not work has more to do with the value of that databinders. After the page renders view the html source and see if the databinder.eval is returning what you intend it to return
