<input type="text" runat="server" ClientIDMode="Static" id="StreetNo" class="form-control input-mask-phone"/>
and a submit button for submitting all data :
<button class="btn btn-info btn-block" style="height: 40px;" OnServerClick="SubmitProject_OnServerClick" ValidationGroup="Date" type="button" runat="server" ClientIDMode="Static" id="SubmitProject"> Submit </button>

/// after submittion
StreetNo.Value = string.Empty;
but nothing happend ..

If a disabled drop-down list is dynamically rendered to the page, it is still possible to use Firebug, or another tool, to tamper with the submitted value, and to remove the "disabled" HTML attribute.
This code:
[code]....
The problem occurs when I use Firebug to remove the "disabled" attribute, and to change the selected option.On submission of the form, and re-creation of the field, the newly generated control has the correct value by the end of OnLoad, but by OnPreRender, it has assumed the identity of the submitted control and has been given the submitted form value.
.NET seems to have no way of detecting the fact that the field was originally created in a disabled state and that the submitted value was faked. This is understandable, as there could be legitimate, client-side functionality that would allow the disabled attribute to be removed.
Is there some way, other than a brute force approach, of detecting that this field's value should not have been changed?
I see the brute force approach as being something crap, like saving the correct value somewhere while still in OnLoad, and restoring the value in the OnPreRender. As some fields have dependencies on others, that would be unacceptable to me.

HTML has an input button type to reset all fields in a form to their initial state in one step: <input type="reset" ... />.
Is there a similar simple way to reset all form fields of an aspx page from code-behind? Or is it necessary to reset all controls one by one with TextBox1.Text=string.Empty, TextBox2.Text=string.Empty, etc. ?
Update:
Context is a simple Contact/"Send us a message" page with 8 asp:TextBoxes on the page (where the user enters the name, address, phone, email, message, etc.). Then he clicks on submit, the Onclick message handler in code-behind sends an email to some administrator, and all the form fields the user filled in should be emptied and he gets a notification in a label ("Message sent blabla..."). I want to have the form fields cleared to avoid that the user clicks again on submit and the same message is sent a second time.

I was able to find examples throughout the internet that more or less accomplished what I needed to be done, but now I have run into some problems. I need to be emailed the form data when the users submits it and then the user needs to be redirected to a thank you page, in this case "thanks.asp". I have been unable to get the form to redirect users to the thanks page, and in my efforts I think I might have messed the email process up as well.

I have entries for an enumeration stored inside a database table with only the following fields: ID and Name. I want to show the values stored inside this table inside a DropDownList on a form. The user then chooses a value and submits the form.
I found a way to easily create a DropDownList from an enumeration (although it would probably be best to just populate the DropDownList with the Name fields of all the records in the table). However, I haven't found a way to later bind the DropDownList in the form submission to an integer value to put into the database (FK - PK) with the other form values.
is it possible to fetch DropDownList content via AJAX and have it be put into the DropDownList and into the SelectList in the ViewModel (with both the ID and Name parameters)? I want to selectively fetch content based on an input the user makes and I want the ViewModel to then be filled with that fetched data.

point me to a source where I can learn to create a form using dropdown, radio buttons, and other controls and then have web users submit information to me via email or post to SQL database so that it can be used. Do I need to be looking for sources via other languages such as php or javascript or can this be done easily using asp.net and visual studio.

I am building a simple support call system and part of the system requires that the engineer go in and update any calls he/she is working on. What I was wanted to do was make it so that when the engineer types in all his info and then hits update, the formview not only posts the data he/she has added to the database but also then sends an email to the user with the updated details.

If I were using PHP I could submit a form to a new page, or the same page, and get the posted variables by doing something such as $_POST['txtVariable'], how do I do the same thing in ASP.NET? And is it possible to have more than one form per page?

I am having problem with multiple clicks on submit button. Multiple clicks cause duplicate record insertion in database. On the form, I have used validation controls. Also I have to make some validations at server side, so I can't use javascript to prevent multiple clicks.

I have a combobox that is used as a control for Formview, so when the user selects a name from the combobox the data in formview displays in edit mode. However, some if the data that is displayed in formview needs to be empty. For example if the Date is being pulled in, it needs to be empty or null in edit mode.

I have a web forms web application (asp.net 2.0). When the user submits the form I have the submit link actually going away so they can't submit it again. However, they could press F5 and that is causing another insert into the database, which I don't want to have happen.
Is there a setting of some sort that I can set if/when they do press F5 to tell the page - don't submit again?

My web app has payment form that need to be submitted to another ASP.NET page (lets call it http://vendor.com/getpay.aspx)residing on another server.
That page will do some mumbo-jumbo works and then redirects it to the acutal
payment gateway site.
when i post my payment form to getpay.aspx via simple HTML form, it works and redirects fine.
if i change the form and its hidden inputs to server side controls, it doesn't work. their page is throwing viewstate exception.
I need the form hidden inputs to be server controls so that i can bind some values generated by my code behind.(i think i can do this like the classic asp way using <%= %>, but it is like going back in standard!)
I tried HttpWebRequest in the code behind, it posts the form but the browser doesn't redirect to Payment Gateway page. I am posting the payment info over non https, how can i prevent the user tampering with the posted data?.I want to validate the payment form in the backend then post it, i couldn't trust the user input data.Also the result was returned to my redirect page with query strings appended. It is also happening over the non https. how much i can trust this redirect data?

I have an asp.net page in an iframe where all links target _blank
<base target="_blank" />
But I want the form on it to submit to _self (i.e. the iframe where the page is located) when the one button is clicked. The form is an <asp:Panel> with an <asp:Button> control for submitting it.
Where can I set the target for this form? Since there isn't a <form> tag or an <input> tag in the file (ASP.NET makes them when it renders the page), I don't know how to change the target to override my <base> tag.
