How to write value to html field from asp.net code behind

I have made an application in javascript using HTML fields in asp.net, as asp text boxes w开发者_开发知识库ere disturbing the ids, so i used html fields, which are working fine with javascript, now i want to fetch database table columns on page load, and want to assign to html fields, what is the best way to do so? Help me!!!!


You could go back to using the ASP TextBoxes and access the ids in JavaScript as follows:

<%= IDofTextBox.ClientID %>

It's probably the easiest as naturally they can then be accessed in the code behind very easily.


you can use asp text boxes fine if you grab a reference in your javascript to their asp.net generated ID via <%= textboxname.ClientId %>


This is not the right way to do it (I wouldn't recommending it), but if its what you need, then it will work.

Add method="post" action="<your path here>" to your form element and when the submit button posts, you will be able to access all the form variables like so:

string txtName = Request["TextBox1"] ?? string.Empty; //replace textbox 1 with text box name

Just be sure to replace the action in form to your page etc..

But really, going back to <asp:TextBox... will save you a lot more time and as Ian suggested, you can access them with javascript by the server tags <%= TextBox1.ClientId %>

ps: also, the ?? is a null coalesce character. its a short form of saying

if(Request["textbox1"] != null)
    txtName = Request["textbox1"];
else
    txtName = "";


If I understand you correctly. You just need to add runat="server" and id="someName" to the html fields and access them in the code behind by its given id.
