Hi,

From your given code i can understand that you have ProductImage and ProductName is a property of ProductClass.

If so, you can use Default value like ProductImage ="NoImage.jpeg". And you should also have such image in your specified folder.

Now when you are not assigning any value to ProductImage, it will display default image.

Hope i answer your query
Thanks

AmitGajjar 1-Sep-12 2:39am

And even you also have done correctly. Check if Eval("ProductImage") returns empty ?

Yes ProductImage is a field in database. I want o make such code as if database Productimage field is empty then show noimage.jpeg

You can also do that in RowDataBound event.

ravi sharma11 1-Sep-12 3:25am

It's ItemDataBound. Can you give an example how to do it?

the below code will help if the information is coming from a database, if not then try playing round with it to see if you can work it out.
rsNews = select statement

XML

<%if isnull(rsNews("News_Image")) then%>
                                            <img src="images/thumbnails/default image.jpg">
                                            <%else %>
                                            <img src="Image_Display.asp?News_Article_ID=<%=rsnews("News_Article_ID")%>" id="news_image2"
                                                alt="LatestNews" border="0" height="70" name="logo_link0" title="Echo_Images"
                                                width="80" align="middle">
                                    </a>
                                    <%end if %>

or you could always try:

XML

ImageUrl=<%#Eval("iPath")%>

and then on the code begin it would be something like:

XML

Function GetNews() As System.Data.DataSet

        Dim dataSet As New DataSet
        Dim connectionString As String = "server='xxxxxx';Database='xxxxxx';User ID='xxxxxx';Password='xxxx'"
        Dim queryString As String = "SELECT [x], [image], [image_name], [b], [v], [e], [q], [w], [r[t],'' As [iPath],Image_name, (CASE  WHEN Image IS NULL THEN 0 ELSE 1 END)as Image_Exists FROM [tblX] WHERE (([Active] = 1)"

        Using connection As New System.Data.SqlClient.SqlConnection(connectionString)
            Dim adapter As New System.Data.SqlClient.SqlDataAdapter()
            adapter.SelectCommand = New System.Data.SqlClient.SqlCommand( _
                queryString, connection)
            adapter.Fill(dataSet)
            For i As Integer = 0 To dataSet.Tables(0).Rows.Count - 1
                If (dataSet.Tables(0).Rows(i)("iPath") = "") Then
                    Dim imgPath As String = ""
                    imgPath = Request.PhysicalApplicationPath().ToString() + "images\location\" + (dataSet.Tables(0).Rows(i)("Image_name")).ToString()
                    'imgPath = "http://?????\images\location\" + (dataSet.Tables(0).Rows(i)("Image_name")).ToString()
                    If (dataSet.Tables(0).Rows(i)("Image_Exists")).ToString = "1" Then
                        'dataSet.Tables(0).Rows(i)("iPath") = "../images/location/" + (dataSet.Tables(0).Rows(i)("Image_name")).ToString()
                        dataSet.Tables(0).Rows(i)("iPath") = "../Image_Display.asp?News_Article_ID=" + (dataSet.Tables(0).Rows(i)("News_article_id")).ToString()
                    Else
                        dataSet.Tables(0).Rows(i)("iPath") = "../images/location/NOImage.jpg"
                        ' dataSet.Tables(0).Rows(i)("iPath") = "http://?????/images/location/NOImage.jpg"
                    End If
                End If
            Next
            Return dataSet
        End Using


    End Function
