Hello,

you can't automatically reference standard HTML tags from your ASP.Net server-side code. To make a HTML control visible to your code-behind you need to add the following 2 attributes to your input control (this same rule applies to most HTML controls running under ASP.Net)
runat="server"

Open in new window

and
id="MyInputBox"

Open in new window

(obviously this id can be any unique name).

i.e. change your input tag to:

<input type=text name="QTitle" size=51 maxlength=100 class=violet id="QTitleTextBox" runat="server">

Open in new window


You can then set the value from your code-behind as:

QTitleTextBox.Text = "MyUserName";

Open in new window


Hope that helps.

P.S. Alternatively you can use ASP Web controls which default these attributes.

Sorry; aren't you talking about a web page?

Web controls in ASP.Net are those that have the tag
<asp: textbox ...>

Open in new window

for example. These are implemented automatically as controls which will runat server and which have control ids. The runat="server" attribute causes actions to automatically execute server code in your code-behind file. These controls are also exposed to your code-behind so that the server can write and read control properties such as .Text for a textbox.

You can apply similar functionality to standard HTML controls by adding the runat="server" and an id attribute as described above.

Not sure if that is what you want.
