RE: passing variables from .aspx.cs code pages to .aspx pages

Hi RadioSignal,

Thanks for your response. Well, from your further description and the code
snippet, I've got the cause of your problem, for ASP.NET server control, we
can't assign the value in their template through
<% %> code block.

also, we can only assign top level property value for ASP.NET controls
through <%# ... %> or <%$ ...%> expressions. And for the
<XXXParameters> in the XXDataSource control, I'm afraid they can only be
delared on page statically, we can't use code expression to add them
dynamically since they're required to be fixed and determined at compiled
time much ealier before our code in <% ... %> get executed. Is there any
particular requirement in your application that you need to dynamically
define paramters for datasrouce control?

Based on my experience, we should always define the parameters statically
in the aspx page's inline template , but we can adjust those parameters'
value at runtime through DataSource control's certain events.

Thanks,

Steven Cheng

| Steven, Thank you for the help, but I am still having problems with these
| parameters. Here is my aspx.cs:
|
| public partial class Test : System.Web.UI.Page
| {
| protected string MyPatientID;
|
| protected void Page_Load(object sender, EventArgs e)
| {
| //What I'd like to do:
| MyPatientID = "13";
|
| //What I have to do:
| TextBox1.Text = "13";
| }
| }
|
| However, in aspx:
|
| <asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$
| ConnectionStrings:MyConnectionString %>"
|
| SelectCommand="SELECT PatientID, BarCode, ChartID, EmpID,
| NameID, Diagnosis, BeginTime FROM Patients WHERE (PatientID = @Param1)">
|
| <SelectParameters>
|
| What I want to do:
|
| <%Param1 = MyPatientID;%>
|
| What I have to do:
|
| <asp:ControlParameter ControlID="TextBox1" Name="Param1"
| PropertyName="Text" />
|
| </SelectParameters>
|
| </asp:SqlDataSource>
|
|
| I am receiving the error - Code block not allowed in this context.
|
| Any ideas how to get access to the MyPatientID variable in the <Select
| Parameters> section?
