Question

Hi,

I'm really struggling with creating an if statement with the content of a data repeater.

I'm looking for somthing along the following lines...

<%IF Container.DataItem( "fldExtraImage1" ) is not dbnull THEN

ELSE IF Container.DataItem( "fldExtraImage2" ) is not dbnull THEN

Below is the code that I need to apply it to...

<%@ Import Namespace="System.Data.SqlClient" %>

<Script Runat="Server">

Sub Page_Load
  Dim conPubs As SqlConnection
  Dim cmdSelect As SqlCommand
  Dim dtrAuthors As SqlDataReader

  ' Retrieve records from database
  conPubs = New SqlConnection( "Server=xyz" )
  cmdSelect = New SqlCommand( "SELECT tblMain.*, tblRetailer.*, tblItem.*, tblItemVersion.fldItemVersion FROM tblMain INNER JOIN tblRetailer ON tblMain.fldRetailerID = tblRetailer.fldRetailerID INNER JOIN tblItem ON tblMain.fldItemID = tblItem.fldItemID INNER JOIN tblItemVersion ON tblItem.fldItemVersionID = tblItemVersion.fldItemVersionID WHERE (tblItem.fldItemTitle LIKE '3' and tblMain.fldNotAvailable is null)", conPubs )
  conPubs.Open()
  dtrAuthors = cmdSelect.ExecuteReader()

  ' Bind to Repeater
  rptAuthors.DataSource = dtrAuthors
  rptAuthors.DataBind()

  dtrAuthors.Close()
  conPubs.Close()

End Sub

</Script>

<html>
<head><title>RepeaterTable.aspx</title></head>
<body>
<form Runat="Server">

<asp:Repeater
  ID="rptAuthors"
  Runat="Server">

  <HeaderTemplate>
    <table border=1 cellpadding=4>
    <tr bgcolor="#eeeeee">
      <th>Retailer</th>
      <th>Items</th>
      <th>Price</th>
    </tr>
  </HeaderTemplate>

  <ItemTemplate>
		<img src="images/Extras/<%# Container.DataItem( "fldExtraImage1" ) %>" alt="<%# Container.DataItem( "fldExtraTitle1" ) %>">
		<img src="images/Extras/<%# Container.DataItem( "fldExtraImage2" ) %>" alt="<%# Container.DataItem( "fldExtraTitle2" ) %>">
		<img src="images/Extras/<%# Container.DataItem( "fldExtraImage3" ) %>" alt="<%# Container.DataItem( "fldExtraTitle3" ) %>">
		<img src="images/Extras/<%# Container.DataItem( "fldExtraImage4" ) %>" alt="<%# Container.DataItem( "fldExtraTitle4" ) %>">
		<img src="images/Extras/<%# Container.DataItem( "fldExtraImage5" ) %>" alt="<%# Container.DataItem( "fldExtraTitle5" ) %>">
  </ItemTemplate>



  <FooterTemplate>
    </table>
  </FooterTemplate>

</asp:Repeater>

</form>
</body>
</html>

Any help on this would be greatly appreciated.

void Repeater_ItemDataBound(Object Sender, RepeaterItemEventArgs e)
        {

           if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
               Image myImage = (Image)e.Item.FindControl("img1");

                if( string.IsNullOrEmpty(myImage.ImageUrl) )
                {
                    myImage.ImageUrl = "blankImage";
                }

            }
        }

Thanks for the reply. I have tried to put your suggestion in the code and I get...

Source Error:

Line 21: conPubs.Close()
Line 22:
Line 23: void Repeater_ItemDataBound(Object Sender, RepeaterItemEventArgs e)
Line 24: {

Write the below code in the code behind,

protected void Repeater_ItemDataBound(Object Sender, RepeaterItemEventArgs e)
        {
        }
