GridView - If statement for hyperlink or no hyperlink within data presentation

Lets say my data is this in the DB -

Column 1     Column 2          Column 3       Column 4        Column5
date         <description>            $5                INV                 65
date          <description>          -$10
date           <description>           $20             INV                 66

What I what to do is this -

Display the information in a GridView. If INV is present then hyperlink description to 65.pdf. If there is no INV just display everything with no link. 

Basically within the <asp:gridview> code I will need some sort of IF statement for IF Column4='INV' Then

boundfield for Date
hyperlinkfield for column2 linked to column5.pdf
boundfield for column3


All boundfields for Data, column2, and column3

Any help would be great.

How about doing something like this? 

		<asp:hyperlink id="HyperLink1" runat="server" navigateurl="65.pdf" visible='<%# Eval("Column4").ToString().Equals("INV") %>'
			text="Click Here" />

Thanks, Ed

Without playing with that ... does the visible link work like this -

 If true = show a link

If false = display text with no link?

8/25/2008 6:48:45 PM

No, if you still want to show the text even if the HyperLink is not displayed, then do something like this instead: 

		<asp:hyperlink id="HyperLink1" runat="server" navigateurl="65.pdf" text="Click Here"
			visible='<%# Eval("Column4").ToString().Equals("INV") %>' />
		<asp:label id="Label1" runat="server" text="Click Here" visible='<%# !Eval("Column4").ToString().Equals("INV") %>' />

I need to finalize my views and stored procedure but I will test out a variation of this and let you know what happens.

8/25/2008 8:08:35 PM

Ok I am kinda confused -

Here is 1 Row of Data with the column Titles

Date - 2007-01-16
ClientID - 2 
Amount - 1506.00 
Transaction - REF#1 -  Advertising Services Due:  for Mailing: Week 1   (Zones: 1) 
Type - INV 
Invoiceno - 1

How it is displayed in a basic gridview as we speak -

                        <asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource2"
                            Visible="False" AllowPaging="True" Width="529px" PageSize="40">
                                <asp:BoundField DataField="Date" HeaderText="Date" ReadOnly="True" SortExpression="Date">
                                    <ItemStyle Font-Size="Smaller" />
                                <asp:BoundField DataField="Transaction" HeaderText="Transaction" ReadOnly="True"
                                    <ItemStyle Font-Size="Smaller" />
                                <asp:BoundField DataField="Amount" HeaderText="Amount" ReadOnly="True" SortExpression="Amount">
                                    <ItemStyle Font-Size="Smaller" />

What I want to happen is this -

Date, Transaction and amount are displayed.

If Type = INV then transaction needs a link to Invoiceno.pdf
If Type != INV just list transaction with no link.

The data is a union select of data for INV, BB, NSF etc. Displaying all account activity for a client. If its an INV there is an associated Invoice we are linking too.

Just trying to push this back up so its not lost.

8/27/2008 1:59:59 PM

This is where I am at with this. I get some errors -

		                                <asp:hyperlink id="HyperLink1" runat="server" navigateurl="<%# Eval("invoiceno") %>.pdf" text="<%# Eval("transaction") %>"
			                            visible="<%# Eval("Type").ToString().Equals("INV") %>" />
		                                <asp:label id="Label1" runat="server" text="<%# Eval("transaction") %>" visible="<%# !Eval("Type").ToString().Equals("INV") %>" />
2 server tag is not well formed.

and 1 Error 3 Leading '.' or '!' can only appear inside a 'With' statement. C:\Asp.Net\WebSite1\Default.aspx 1 1 C:\Asp.Net\WebSite1\

Which references the top of my page?

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>


8/27/2008 2:41:45 PM

This is what you want then for VB.Net: 

		<asp:hyperlink id="HyperLink1" runat="server" navigateurl="<%# Eval("invoiceno") %>.pdf"
			text="<%# Eval("transaction") %>" visible="<%# Eval("Type").ToString().Equals("INV") %>" />
		<asp:label id="Label1" runat="server" text="<%# Eval("transaction") %>" visible="<%# Eval("Type").ToString() <> "INV" %>" />

  <asp:label id="Label1" runat="server" text="<%# Eval("transaction") %>" visible="<%# Eval("Type").ToString() <> "INV" %>" />




8/27/2008 3:09:40 PM

How about this? 

		<asp:hyperlink id="HyperLink1" runat="server" navigateurl='<%# Eval("invoiceno", "{0}.pdf") %>'
			text='<%# Eval("transaction") %>' visible='<%# Eval("Type").ToString().Equals("INV") %>' />
		<asp:label id="Label1" runat="server" text='<%# Eval("transaction") %>' visible='<%# Eval("Type").ToString() <> "INV" %>' />

Data presentation without a data control

Or is it a new standard to always use one of the new data controls. If the answer is yes, would you still use an SQLDatasource, or would you set up the connection in code?
