Hello Everyone,



A very basic question.  When using ASP, you can set the value of a form 

field like value="<%=varValue%>".  I am unclear as to the "proper" way to 

do this with ASP.Net in order to get maximum performance.  Also, I am 

confused with regards to the state of these values as they are passed from 

page-to-page.  In the examples I have seen, the state is retained from 

page-to-page without using any type of "value" tag.  If I use a "value" in 

the form, will this mess up the state?  Could someone point me to some 

code examples.  Thanks for the help in advance.

I am pretty new to .net as well but here is one way to do it.



this would be in the body

<form runat="server">

<input type="text" id="Name" runat="server" /><br>

<input type="text" id="Email" runat="server" /><br>

<input type="submit" value="submit">

</form>



You would want to bind values to these in the Page_Load

this is using C#, the syntax is a bit different for vb.net



void Page_Load(Object Source, EventArgs E)

{

  string iID;

  iID = Request.Params["ID"];  // use () instead of [] in vb  

  

  // left out all db connection and db command code





  try

  {

    // load DataReader

    oDataReader = oCmd.ExecuteReader();



    // open

    oDataReader.Read();



    // bind values to input fields based on id

    Name.Value = oDataReader.GetString(0);

    Email.Value = oDataReader.GetString(1);

		

  }

  catch

  {

    Name.Value = "";

    Email.Value = "";

  }

  finally

  {

    oDataReader.Close();

    oDataReader = null;

    oCmd = null;

  }

}



I beleive you could also use Web Forms in place of input type="text"

<asp:TextBox id="Name" runat="server" /><br>

<asp:TextBox id="Email" runat="server" /><br>

but you would set the Text property not the Value property



Name.Text = oDataReader.GetString(0);



hope this is of some help.

it looks like you can use the syntax



<input type="text" value="<%# sValue %>" name="Name" runat="server" />



in your script tags you would have to declare sValue outside any functions



string sValue;



then set the value in the Page_Load function

void Page_Load(Object Source, EventArgs E)

{

  sValue="Hello World";

  // it won't work unless you call DataBind()

  Page.DataBind();

}
