Opening window from a grid

[Clive Hoggar]

Hi
I hope someone can help - I think I am list in syntax issues with this.
Trying to use showWindow(url) method to pass a record ID to the window.

I have this column in  a radgrid:

<telerik:GridTemplateColumn DataField="ID" DataType="System.Int32" SortExpression="ID" UniqueName="ID">
    <ItemTemplate>
      <asp:HyperLink ID="HyperLink1" runat="server"
        NavigateUrl='<%# "javascript:onclientclick=showWindow('../podcast-player/play-podcast.aspx?ID=" & Eval("ID") & "');" %>'>Listen</asp:HyperLink>
       </ItemTemplate>
</telerik:GridTemplateColumn>

and my javascript and window declaration:

<script type="text/javascript" language="javascript">
     function showWindow(url) {
         var oWnd = $find("<%=RadWindow1.ClientID%>");
         oWnd.setUrl(url);
         oWnd.show();
     }
     function OnClientClose(oWnd) {
         oWnd.setUrl("about:blank"); // Sets url to blank
     }
</script>
<telerik:RadWindow ID="RadWindow1" runat="server" Skin="Vista" Behaviors="Move,Close,Resize" VisibleStatusbar="False"
Animation="Fade" Height="170px" Width="280px"
                    OnClientClose="OnClientClose">
                </telerik:RadWindow>

The problem is 'the server tag is not well formed' at runtime.   I tried replacing the regular apostrophes inside the showWindow('....') with a different type of apostrophe (`), which removed the runtime error message, but the link does not do anything when clicked.

Please help me out of the syntax (I think) mire!

Thanks

Clive

Hello Clive,

Try out the following code snippet.

ASPX:

<telerik:GridTemplateColumn DataField="ID" DataType="System.Int32" SortExpression="ID"
        UniqueName="ID">
        <ItemTemplate>
            <asp:HyperLink ID="HyperLink1" runat="server">Listen</asp:HyperLink>
        </ItemTemplate>
    </telerik:GridTemplateColumn>

CS:

    protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem) e.Item;
            HyperLink editLink = (HyperLink)e.Item.FindControl("HyperLink1");
            editLink.Attributes["href"] = "#";
            editLink.Attributes["onclick"] = "return ShowEditForm('Default.aspx?id=" + item.GetDataKeyValue("ID").ToString() + "');";
        }
    }

[Note: Set the DataKeyNames as ID in order to get the DataKeyValue]
