Strange Behavior from RequiredFieldValidator (and Two LinkButtons)

We have an ASP.NET web form with 1 TextBox, 2 LinkButtons, and 1
RequireFieldValidator. The situation is: the user needs to enter a folder
name in the TextBox and click the first LinkButton (the Create Folder
LinkButton) to create the folder. Then once that's done, they need to click
the second LinkButton (the Next LinkButton) to go to the next page (a
rudimentary wizard).
The RequiredFieldValidator is there to make sure the user enters a folder
name in the TextBox before clicking the first LinkButton (the Create Folder
LinkButton). This all works fine.
What's strange is if the user doesn't enter anything in the TextBox and
clicks the second LinkButton (the Next LinkButton) before clicking the first
LinkButton (the Create Folder LinkButton), the RequiredFieldValidator alarms
the error anyway.
Is this correct behavior? What we want is for the first LinkButton (the
Create Report LinkButton) only to validate that text has been entered in the
TextBox, not the second LinkButton (the Next LinkButton). How can we do
this?Hi JJ,
The function of the requiredfield validator is just to check the txtbox is
having some value or not.
If you want that checking has to be made only for the first link button and
not for the second link button, then specifically you have to inform the
validator as follows.
1. Click the second link button and go to the properties window.
2. Set the cause validation property to False.
So, here after when you are click second link button form will not do any
validations.
Hope this helps you.
Cheers,

Strange Characters

Hello,

When I click submit the text in the textbox changes.
For example "Andr=E9 Sousa" becomes "Andr=C3=A9 Sousa"
What is wrong and how can I solve this?
Thanks,

Whenever one "unusual" character gets substitued by two even more "unusual"

Strange problem

I Have a strange problem. I have build a form in wich are some controls. Two textbox and one dropdown control.
The user can perform a search selecting a value in dropdown or inserting in textbox and click on search button.
My sub verify if dropdown control or textbox changed and build sql string.
But the strange think is that all run only when I use dropdown. If I insert value in textbox and not dropdown search don't work.
The code don't run. Why?
I have inserted OnTextChanged event in textbox html code and OnSelectedIndexChanged in dropdown html code but nothing to do!
HELP ME, PLEASE!You need to post your code so we can help you.

Strange problem setting focus on a TextBox within a WizardStep.

For testing purposes i have got a 2 step WizardControl. Eqach step contains
a text box, TextBox1 and TextBox2 respectively. If i put the following code
in the respective activate event handlers for the two steps,

TextBox1.Text ="foo";

and

TextBox2.Text = "bar";

Then in the first step the TextBox (TextBox1) contains the word foo and in
the second step the TextBox (TextBox2) contains the word bar. As you would
expect.

However if i replace the code with

TextBox1.Focus();

and

TextBox2.Focus();

Then i get the following error and i can't understand why. This is the
first time i have used Wizard controls and i'm just trying to work out how
they behave. What am i missing about Wizard controls that is causing this
behaviour.
