User Control Question

[emblewembl]

Hi, I am new to asp.net so forgive me if this is a dumb question! I have just created a user control which is very simple and is basically just a header which will go on each page of my site. The code is as follows:

<%@ Control Language=&quot;VB&quot; %>
<table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; width=&quot;100%&quot; border=&quot;0&quot;>
    <tbody>
        <tr>
            <td>
                <img src=&quot;images/topImage1.gif&quot; /> 
            </td>
            <td>
                <asp:label class=&quot;SectionText&quot; id=&quot;SectionName&quot; runat=&quot;server&quot;></asp:label>
            </td>
        </tr>
        <tr>
            <td colspan=&quot;2&quot;>
                <img src=&quot;images/topImage2.gif&quot; /> 
            </td>
        </tr>
    </tbody>
</table>

In the page where I am using this control I set the text of SectionName in the Page_Load sub, as follows:

     'Set up text for section heading
     SectionName.Text = "NEW ORDER"

However, although this worked before I turned the header into a user control, it doesn't anymore, and I'm guessing I need to set the text value in a different way or place. Can you tell me how? The error I get is:

Compiler Error Message: BC30451: Name 'SectionName' is not declared.

Source Error:

Line 30:
Line 31: 'Set up text for section heading
Line 32: SectionName.Text = "NEW ORDER"
Line 33:
Line 34: DateToday.Text = today

Remember that everything is now Object Oriented. Think of your user control as just another class. SectionName is a private variable representing a label class for your user control class.

So to set it you need to define a property for that method.

If your only setting and not ever reading it back then this will work.

Public WriteOnly Property SetSectionName()
Set(ByVal Value as String)
SectionName.Text = Value
End Set
End Property


Then in your page code-behind access the id you gave the user control .SetSectionName = whatever

And thats that That'l do donkey, that'l do

Hi Mark,

I tried to follow your example here (in C#) but with no luck.

Can you help?

------------------------------------------
Here is my Header.ascx file:

<%@ Control %>
<!-- Standard Header for MCLNO pages -->

<script language=&quot;C#&quot; runat=&quot;server&quot;>

public string SectionValue(string Val) {

set {
SectionName.Text = Val;
}

} //end SetSectionValue property



</script>

<!-------------------------------------------------------->

<table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; width=&quot;100%&quot; border=&quot;0&quot;>
<tr>
<td colspan=&quot;4&quot;>
<img src=&quot;/hcsd/mclno/images/lsuhsc-hcsd-mclno-banner.jpg&quot; border=&quot;0&quot; />
</td>
</tr>
<tr>

<asp:label class=&quot;SectionText&quot; id=&quot;SectionName&quot; runat=&quot;server&quot;></asp:label>

</tr>
</table>

--------------------------------------------------------

Here is my default.aspx file:

<%@ Page Language=&quot;C#&quot; Debug=&quot;true&quot; Trace=&quot;false&quot; %>
<%@ Register TagPrefix=&quot;MCLNO&quot; TagName=&quot;HEADER&quot; Src=&quot;../user_controls/header.ascx&quot; %>
<%@ import Namespace=&quot;System.Data&quot; %>
<%@ import Namespace=&quot;System.Data.SqlClient&quot; %>
<%@ import Namespace=&quot;System.IO&quot; %>
<%@ import Namespace=&quot;System.Web&quot; %>
<script runat=&quot;server&quot;>

public void Page_Load(Object sender, EventArgs e) {

UserControl1.SectionValue = &quot;<td width=\&quot;10%\&quot; align=\&quot;center\&quot; class=\&quot;titleText\&quot;>History</td>&quot;

if (!IsPostBack) {
string myConnection = ctlConnectStrings.SQLConnectionString;
SqlDataAdapter myCommand = new SqlDataAdapter(&quot;MCL_getMenu&quot;, myConnection);

myCommand.SelectCommand.CommandType = CommandType.StoredProcedure;
DataSet ds = new DataSet();
myCommand.Fill(ds, &quot;Menu&quot;

}
} //end Page_load



</script>

<!--------------------------------------------------------------------------->

<HTML>
<HEAD>
</HEAD>
<BODY>

<MCLNO:HEADER id=UserControl1 runat=&quot;server&quot;></MCLNO:HEADER>


<MCLNO:FOOTER id=UserControl2 runat=&quot;server&quot;></MCLNO:FOOTER>

</BODY>
</HTML>

------------------------------------------------------

My goal is to set the label in the ascx file with the string (a <td> tag) to be placed into the table HTML of the header.

I get a compilation error saying ';' is expected on the &quot;set&quot; statement in the user control.

Any suggestions?

Thanks,
JC

I got it to work!

I simply changed my user control to look like:

<%@ Import Namespace=&quot;System.Data&quot; %>
<%@ import Namespace=&quot;System.IO&quot; %>

<script language=&quot;C#&quot; runat=&quot;server&quot;>

public string SectionValue {

set {
SectionName.Text = value;
}

} //end SectionValue property



</script>

<!-------------------------------------------------------->

<table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; width=&quot;100%&quot; border=&quot;0&quot;>
<tr>
<td colspan=&quot;4&quot;>
<img src=&quot;/hcsd/mclno/images/lsuhsc-hcsd-mclno-banner.jpg&quot; border=&quot;0&quot; />
</td>
</tr>
<tr>

<asp:Label id=&quot;SectionName&quot; runat=&quot;server&quot;></asp:label>

</tr>
</table>
