OnKeyUp event in ASP.Net

How about the text entered by you in the textbox (ASP.NET) should be postback and the every entered char should be read in Code Behind class.\

It might be used for look up instantaneously in DB.Table.

This is done by calling the OnKeyUp event.

Sample code snippet.

   protected void Page_Load(object sender, EventArgs e)  
   {     
     TextBox1.Attributes.  
             Add("onkeyup",Page.  
             ClientScript.  
             GetPostBackEventReference(TextBox1, ""));      
     Response.Write(TextBox1.Text);  
   }

It is possible to hand out a raw pointer to a managed object. But to do so, you effectively need to the tell the CLR the object should not be moved in memory while something(for example, a native code component used in interop) holds on to the pointer. The task of doing this is called pinning and
is a specialized concept typically used only in interop scenarios.
