If Then statement inside of repeater control

[Guest]

Hello,

I am trying to use an If Then statement inside of a repeater control.
However, I am getting the following error:
Expression expected.

Any help would be appreciated.

Thanks in advance,

sck10


<asp:Repeater id="rptWebDocList" runat="server">
<HeaderTemplate>
<table border="1">
</HeaderTemplate>
<ItemTemplate>

<%# If Container.DataItem("Status") = " Total Not Reworked" Then %>

<tr><td width="280" colspan="3"><hr color=#0000FF></td></tr>
<tr>
<td width="120"><%# Container.DataItem("Status") %></div></td>
<td width="80"><%# Container.DataItem("StatusCount") %></div></td>
<td width="80"><%# Container.DataItem("PercentTotal") %>%</div></td>
</tr>

<% Else %>

<tr>
<td width="120"><%# Container.DataItem("Status") %></div></td>
<td width="80"><%# Container.DataItem("StatusCount") %></div></td>
<td width="80"><%# Container.DataItem("PercentTotal") %>%</div></td>
</tr>

<% End If %>

</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater></div></td>

Rather than trying to put a conditional statement in the <ItemTemplate>,
instead call a function from the <ItemTemplate>, passing in the
databound values that determine and are part of the output.

In your code portion, create a function with the same name and takes in
the same inputs, and returns a string. The string returned will be what
is displayed in the <ItemTemplate>

This explanation may not be that clear, but the following FAQ should
help: http://tinyurl.com/6muyn

It shows how to have the output customized based on a single field, but
the helper function could have an If statement and return a much more
complex HTML string.

Hi Sck10,

Thanks for your posting. As for the problem you mentioned, here are some of
my understandings:
1. The<% %> expression is only used in page(or UserControl, ascx) 's page
level template , but unable to be used in any asp.net web server control's
databinding template. We can only use <%# %> databinding expression to
bind value to asp.net server control's properties or template. For example:
<asp:TextBox ... Text="<% ...%>" ...> is not allowed,

we should use <asp:TextBox ... Text=<%# .. %> ..>
Also, the expression or code will be called when the TextBox (or its parent
container )'s DataBind method is called.

2. As for your problem, I think you should put the If ...else statement
logic into the <#% %> block . Forexample:

<ItemTemplate>

<%# GetHeader( Container.DataItem("Status") ) %>

<tr>
<td width="120"><%# Container.DataItem("Status") %></div></td>
<td width="80"><%# Container.DataItem("StatusCount") %></div></td>
<td width="80"><%# Container.DataItem("PercentTotal") %>%</div></td>
</tr>


</ItemTemplate>

GetHeader( string) is a helper function defined in the codebehind class
which return the correct html depend on the input param. such as:

#must be protected or public so that we can call it in aspx page's inline
code
protected string GetHeader(string status)
{
if(status== xxx)
{
return "<tr><td width=\"280\" colspan=\"3\"><hr
color=#0000FF></td></tr>";
}else
{
return string.Empty;
}
}


Hope helps. IF you have anything else unclear, please feel free to post
here. Thanks.

Hi all,


I have a similar case and I am using a datalist instead of reapeater. How do evaluate an xml data item (itemStatus) and change it (itemIndicator) content before binding ? Says , if itemStatus = in stock, I want to change out that item indicator to a different flash object. If itemStatus= not in stock, another flash object will be used? Thanks


Here is my code:

<form id="Form2" runat="server">
<aspataList BackColor="#d5d5d6"
id="cdcatalog"
RepeatColumns="4"
RepeateDirection="Horizontal"
gridlines="Both"
runat="server">

<ItemTemplate>
<%#Container.DataItem("itemTitle") Container.DataItem("itemIndicator")%%>
</ItemTemplate>

</aspataList>

xml
<catalog>
<cd>
<itemTitle>Empire Burlesque</itemTitle>
<itemStatus>in stock</itemStatus>
<itemIndicator>
<![CDATA[<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" width="12" height="12" id="blinking_red" align="middle">
