I have an html input text that I am trying to set from codebehind. how do I do this?

aspx page:
<input id="CustomerName" value="<%= strCustomerName %>"/>

aspc.cs page:

class...
{
string strCustomerName ="test";

   protected void Page_Load(object sender, EventArgs e)
    {
      try
      {
          strCustomer = "this doesn't work";
.....

I get the "test" but not the "this doesn't work" - I'm guessing a protection level/page scoping problem?

any help would be greatly appreciated....

<input id="CustomerName" runat=server>

from code-behind:

CustomerName.Text = "text";

In order to access is from code-behind you need to add a runat="server" attribute to it. This way the runtime will wrap it as a GenericControl and allow you to set its properties from code-behind as you would with any standard server control.

ah, ok, thanks!

I seem to get both the suggestion above working now. But this also works...
class...
    public string strCustomerImpact = "";
 
page_load
           strCustomerImpact = "customer impact";
 
aspx:
 <textarea id="txtCustomerImpact" cols="60" rows = "5"                  
                                   readonly="readonly"><%= strCustomerImpact %></textarea>

If I wanted to send the contents of my aspx page in an email, which method would render properly, or both as they both generate html on running?

thanks!

I recommend using the code-behind approach.
