Namespace:   System.Web.UI
Assembly:  System.Web (in System.Web.dll)

public string Text { get; }

Property Value

Type: System.String

A String that represents the text content of the DataBoundLiteralControl.

The DataBoundLiteralControl class persists the value of its Text property to view state.

The following code example creates a custom control and uses that control from within an .aspx file to display the text of a DataBoundLiteralControl object. The custom control obtains a DataBoundLiteralControl object and outputs the text property in its Render method.


using System;
using System.Web;
using System.Web.UI;

namespace Samples.AspNet.CS.Controls 
{

   public class MyControl : Control 
   {

    [System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.Demand, Name="FullTrust")] 
    protected override void Render(HtmlTextWriter output) 
    {
      // Checks if a DataBoundLiteralControl object is present.
      if ( (HasControls()) && (Controls[0] is DataBoundLiteralControl) ) 
      {
        // Obtains the DataBoundLiteralControl instance.
        DataBoundLiteralControl boundLiteralControl = (DataBoundLiteralControl)Controls[0];
        // Retrieves the text in the boundLiteralControl object.
        String text = boundLiteralControl.Text;
        output.Write("<h4>Your Message: " +text+"</h4>");

      }
    }
   }    
}

You can compile the control with the Visual Basic Compiler (vbc.exe) or C# Compiler (csc.exe). You must place the resulting .dll file in the Bin directory of the Web project, as shown in the following code example.

csc /t:library /out:myWebAppPath/bin/cs_myDataBoundLiteralControl.dll myDataBoundLiteralControl.cs

The following code example demonstrates how the custom control is registered and used within an .aspx file.
