display message if gridview has no row issue

Posted By:      Posted Date: October 11, 2010    Points: 0   Category :ASP.Net

(1) i want to show message if no data row is found in the grid. but my code below does not achieve this. basically if gridview shows data then i want my panel (booking form) to be made visible otherwise hidden. the booking form panel is set to visible false. my else statement is not working...

        protected void btnCheckFlightAvailability_Click(object sender, EventArgs e)
            if (Page.IsPostBack)
                this.gvSingleFlightSearch.DataSourceID = "CheckSingleFlightDataSource";

                if (gvSingleFlightSearch.EmptyDataText != null)
                    pnlFlightAvailableMessage.Visible = true;
                    lblAvailableFlights.Text = "Flight Available";
                    gvSingleFlightSearch.Visible = true;


                        pnlFlightAvailableMessage.Visible = false;
                        lblAvailableFlights.Text = "No Flight Available";
                        gvSingleFlightSearch.Visible = false;

display an icon in gridview - selectively


I've created an ExpenseReport application which allows users to attach receipts to Expense Report Lineitems. These are contained in a gridview using a template field:

<asp:TemplateField HeaderText="File" InsertVisible="False">
                    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
                <asp:HyperLink ID="HyperLink" ImageUrl='<%# Eval("filename", "~/workflow/Images/attachment.jpg") %>'
                runat="server" NavigateUrl='<%# Eval("filename", "http://workflowserver/AtWork/workflow/ExpenseReport/retrieveattachment.aspx?attachment={0}") %>' Text="" />  

The trouble I have is that the 'attachment.jpg' icon shows for every lineitem (even one that does not contain an attachment).

I would like to be able to selectively display this icon or show a different icon if there is NO attachment.

Any suggestions would be greatly appreciated. I'm kind of stuck... ;-)

Thank You.

Display image icon in HyperLinkField of Gridview

 Hello everyone! Can someone please tell me how to display an image in a HyperLinkField of a gridview?  Instead of words, I just want to show a simple little icon that can be clicked on and pass a query string to the next page.  The first hyperlink field I have set up works perfectly and passes the querystring to the next page.   The second hyperlinkfield is my attempt at showing the image but it's giving me a squiggly and telling me "the element img cannot be nested within the element hyperlinkfield" I got this technique from this brief article   - I would like to accomplish exactly what it says it is suppose to do. Thanks!   <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="clientID"> <Columns> <asp:BoundField DataField="clientFirstName" HeaderText="First Name" /> <asp:BoundField DataField="clientLastName" HeaderText="Last Name" /> <asp:HyperLinkField HeaderText="More Info" Text="View more info..."

display image in gridview - unlucky with tutorials

I'm trying to display images in a gridview, but after following the examples of maybe 7 different tutorials I still haven't succeded. There are always some things that go unexplained. My latest attempt is according to this tutorial:http://www.aspdotnetcodes.com/Insert_Images_Database.aspxProblem No1: what exactly should I write in my ashx-file? Following the example in the tutorial this is the code so far:<%@ WebHandler Language="C#" Class="ImageHandler" %> using System; using System.Web; using System.Configuration; using System.Data.SqlClient; public void ProcessRequest (HttpContext context) { SqlConnection myConnection = new SqlConnection("DBPejganConnectionString1"); myConnection.Open(); string sql = "Select Image_Content, Image_Type from ImageGallery where Img_Id=@ID"; SqlCommand cmd = new SqlCommand(sql, myConnection); cmd.Parameters.Add("@ID", SqlDbType.Int).Value = context.Request.QueryString["id"]; cmd.Prepare(); SqlDataReader dr = cmd.ExecuteReader(); dr.Read(); context.Response.ContentType = dr["BildTyp"].ToString(); context.Response.BinaryWrite((byte[])dr["BildData"]); dr.Close(); myConnection.Close(); }Please give me a hint (or rather the answer) on what's missing. The rest of the problems comes later... :)

Attempting to use an HTTP handler to display pictures in gridview. It's not working, please help.

I am writing a web page that needs pictures displayed for each item.  The page works just fine except for the pictures.  I have a file called handler.ashx uploaded to the server as well.  It does not seem to be hurting anything, but it doesn't seem to help display the pictures either!  I am working with a MySQL database so I am thinking that the call for the data or the ashx page's structure itself are my problem.  I am using C# Express so there is no generic handler class to autoload and therefore my handler page is pasted together and I know the using statements are in the wrong place, but I'm new to this and I'm lost!  The following is my database table info (table is named: Yamaha), my handler.ashx page code, and the code for the final web page.  I have loaded ".jpeg" or "jpeg" into the field I added called "Image_Type"  since I have already uploaded all pictures as longblobs.  You can view the final web page here: http://www.88867honda.com/YamahaPtsSale.aspx Thanks in advance for any help, Melissa   Table info: Field TypeAttributes--> Null DefaultExtra--> Comments part_number varchar(15)  --> No     -->   description varchar(50)  --> Yes  NULL   -->   qty int(4)  --> Yes  NULL

How to get SPPageStatusSetter to actually display a status message

I have a event listener running on a list, with several possible conditions.  I want to use the status bar to update the user as a case happens.  I thought, that since the code is a event reciever/listener, that this would be considered server side code, and to make something appear on the status bar, I can use the SPPageStatusSetter.AddStatus method to show the message.  Yet, when I put in the method parameters, nothign  happens. (I did a statusbar= new SPpageStatusSetter(), statusbar.AddStatus("caller", "messgae", Yellow)) What am I missing?  Is this not considered server-side code, and I should use the other mechanism to set the status bar?  or? thanks rsRocky Sanders

Problem with GridView display

I have a calendar control where a user selects a date and then inputs info into a FormView control. Underneath the FormView is a GridView that shows all data from the SelectedDate on the calendar control. However, when the date is selected, all the information from the table ( from all dates ) is displayed. Any ideas on why?
