The whole thing is in a form, and it doesnt postback when this button is clicked. Im no good with javascript, but i got a feeling thats not the problem.
I have two text boxes txtBox_Input1 & txtBox_Input2 which Iam trying to validate on a postback when a button is clicked.here is the code:
[Code]....
The issue is that its causing an unhandled exception. When i debug by applying breaks and i check the validatorControl.ControlToValidate the IsValid property is false and then i try to cast the ControlTovalidate which is a string to a TEXTBOX and try change the border properties i get NullReferenceException, i.e. errortxtbox control is null at step '3->'. I check the validatorControl and I have all the attributes there but somehow its not casting the controlToValidate string as an appropriate texbox control to errortxtbox.
I have a web page with 3 search fields on it, each with a different submit button. When using the enter button on the keyboard to submit any of them, an incorrect action is being performed, although with the mouse it's fine. Any ideas why this is happening? The rendered HTML as requested below:

How to make a link button visible after another button has been clicked in asp.net(vb) in button_click()
it says error as "Object reference not set to an instance of an object."
i've done this in my code
Protected Sub InsertButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim receipt As LinkButton = FormView1.FindControl("LinkButton1") [code]....
Obviously I am a total noob and this is simple to some of you, but I can not figure out why the rest of the sub works, but the button1.Text="Uploading, Please Wait..." seems to be completely ignored.
The button is supposed to change text when clicked but no method I have tried works with my page.

I need to change a standard HTML Input button to a Link button but am running into problems because the existing
code calls a javascript function. The function basically does the same as the browser back button. When I add the code and
set the property runat="server" I get a "CS1026: ) expected".
Quite new to ASP,net (VS2010) so could be going about this the wrong way.

I have two buttons on a messaging form. A "To" (who's going to get the message) and "Cc" (who's going to get a copy). The user choose the names from a listbox that popup when the "To" button is clicked. When the user click the "Ok" button the name is moved to the "To" label.If the user now wishes to CC someone how do I get the "ok" button to know I've click the "CC" and not the "To" and to put the name on the "CC" label?I tried switch statement but was not working

On my Search page, I have a search textbox, four drop-down lists and a "Search" button. If I use only the drop-down lists and click the "Search" button, results are immediately returned. However, if I enter text into the textbox and click the "Search" button, nothing happens until I click the "Search" button a SECOND time.The processes that occur for the latter scenario are as follows:Text entered into textbox, and Search button clicked:On FIRST click attempt:
1. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Search.aspx is called
2. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Main.Master.vb is called
3. Process stops! No results
On SECOND click attempt:
1. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Search.aspx is called
2. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Main.Master.vb is called
3. Protected Sub SearchSubmit(ByVal sender As Object, ByVal e As EventArgs) Handles btSearch.Click for Search.aspx is called
4. Search continues and completes.
So, why will the 3rd step not kick in until clicking Search for a second time

I would like to program an Input Box that comes up when a user clicks 'Find' button. It asks 'Please enter an employee number'. Then it takes the employee number typed into a text box and searches a dataset for that specific employee record.
I know that it should be server side because the client may not have the proper javascript installed or diabled. Therefore, can someone give me some code to put in code behind that can pop up an input box and use the input after, if this can be done?
