Binding Variable in asp.net

Question

Problem:

Exception Details: System.Data.EntitySqlException: The query syntax is not valid. Near term '<', line 8, column 16.

Code Behind:

    protected void Page_Load(object sender, EventArgs e)
    {

        int Id = 3;

        Page.DataBind();
    }

project.aspx.cs

<asp:EntityDataSource ID="ProjectEntityDataSource" runat="server" ConnectionString="name=DBEntities" DefaultContainerName="DBEntities" EnableFlattening="False" EntitySetName="projects" Select="it.[Id], it.[ClientId], it.[Name], it.[Description]"
    Where="it.ClientId = <%# Id %> " >
</asp:EntityDataSource>

What i have tried: ASP.NET databinding / getting variables from codebehind

I know it's too easy but i'm not able to figure out where the problem really is why i'm not able to bind the code behind data.Thanks!

You can take help of the following example In your case

protected void Page_Load(object sender, EventArgs e)
{
     ProjectEntityDataSource.WhereParameters["Username"].DefaultValue ="3";
     Page.DataBind();
}

aspx

<asp:EntityDataSource ID="ProjectEntityDataSource" runat="server"
     ConnectionString="name=DBEntities" DefaultContainerName="DBEntities" 
     EnableFlattening="False" EntitySetName="projects" Select="it.[Id], it.[ClientId], 
     it.[Name], it.[Description]" Where="it.ClientId = @Username">
      <WhereParameters>
        <asp:Parameter Name="Username" Type="String" />
    </WhereParameters>
</asp:EntityDataSource>

<asp:EntityDataSource ID="ProjectEntityDataSource" runat="server" 
    ConnectionString="name=DBEntities" DefaultContainerName="DBEntities" 
    EnableFlattening="False" EnableInsert="True" EnableUpdate="True"      
     EntitySetName="projects" Where="it.ClientId= @Id"  >
    <WhereParameters>
        <asp:QueryStringParameter Name="Id" Type="Int32" QueryStringField="Id" />
    </WhereParameters>
</asp:EntityDataSource>
