POJavascript function call from ASP .NET Hyperlink NavigateURL property
text
Body
copied!<p>I have a ASP table that I create dynamically on the page load event. In that event, I populate the ASP table with titles and then a ASP .NET Hyperlink control that points to a .ashx page to serve up a file for the client to download. </p> <p>For particular files (image files), I'd like to kick off a javascript function to open a new window with that file displayed in it. I have all the code to do this, but I can't get my Javascript function to work in the hyperlink NavigateURL property. I'm very new to Javascript, so I'm not sure what I'm missing. Can I do what I'm trying to? Can I not use the table control? </p> <p>ASP code behind</p> <pre><code>Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim iWineID As Integer If Not Integer.TryParse(Request.Params("WineID"), iWineID) Then Throw New InvalidOperationException("Invalid request") Me.lblWineName.Text = Utils.GetWineName(iWineID) Dim dtDocs As New dsDocs.docsDataTable Using taDocs As New dsDocsTableAdapters.docsTableAdapter dtDocs = taDocs.GetDataByProdIDOrWineID((Utils.GetProducerIDByWineID(iWineID)), True, iWineID) End Using If dtDocs.Rows.Count = 0 Then Me.lblDocsFound.Text = "No documents available for this wine."
