C# - Efficient / Easy Method To Validate For Empty Text Boxes?
Oct 1, 2010
I have a about 6 or 7 text boxes which needs to be validated to make sure they are not empty from server side code. So how I usually do this is, check each textbox 1 by 1 to ensure that they are not empty. Are there any other efficient methods to do this? I have searched on SO and have found out that adding all the textboxes to a list and using a for each is a much better method. Are there any other ways that this can be achieved? Thanx a lot in advance :)

I've problem with validating all text boxes in PlaceHolder. I made PlaceHolder and I've no idea how to check that all textboxes have integer numbers as a text.
public void Made_Matrix (PlaceHolder Matrix, int Size){
for(int row=0; row < size; row++){
for(int col=0; col < size; col++){
TextBox TB = New TextBox();
Matrix.Controls.Add(TB);
TB.ID = TB + Convert.ToString(row) + Convert.ToString(col);
TB.AutoPostBack = "true";
}
Matrix.Controls.Add(new LiteralControl ("<br/>"));
}
}
public void TB_Validate (PlaceHolder Matrix, int Size){
for (int row = 0; row < size; row++){
for (int col = 0; col < size; col++){
string Ident = TB + Convert.ToString(row) + Convert.ToString(col);
how can i find text hidden in TextBox with ID from Ident? And how to check if it's numeric? I suppose that in .NET there's no function like IsNumeric(), am I right?

I have an ASP.NET gridview where I allow the user to edit a record. I need to validate multiple fields as one. I need to require that the user either enter a first and last name OR a company name. All three cannot be blank. Most of the sample code I am finding does not address the text boxes only being visible while the gridview is in edit mode. When not in edit mode, the text boxes do not exist so
document.getElementById('<%= editFirstName.ClientID %>') throws an error upon page load.

Meaning only one of them can have a value, but not both.
I suspect one validation control can't handle both.

Is there one simple test that a person can do that covers all options where there could be a null, or "" value. When I google, I see so many options. I see:
if txtBox1.text IsNot nothing
if txtBox1.text.toString isNot nothing
if txtBox1.text <> ""
if txtBox1.text.toString <> ""
if isNull(txtBox1)
Is there on test that can cover them all?

I am trying to figure out how to get the text value from each textbox on a page that has a dynamically created number of text boxes. I need to store that value in a database row. I guess what i need is to be able to store the text box values in a collection or arrary of some sort and then be able to use textbox(i).value or something of that nature. Not really sure where to begin.

I would like to validate the textbox for specific text and it must not be blank. But the regular expression validator is not validating if the text box is BLANK. However, it validates if I type something in the text box.
How can I make regular expression to trigger even if the text box is empty?
Should I use Required Validator + Regex Validator at the same time?
<asp:TextBox ID="txtcard" runat="server" MaxLength="16"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator2" runat="server"
ControlToValidate="txtcard" ErrorMessage="Please type credit card no"
ValidationExpression="^d{16}$"></asp:RegularExpressionValidator>

Is it possible to set the start location of all these text boxes to be the same? Currently Two and Three are aligned together, but one is not. They are all inside their own div tags as well, not sure if that will matter. The only thing that does matter is the start of each text box needs to be aligned.
Code:
<div class="One">
<font class="BoldTextBlack">Option One:</font>
<asp:TextBox runat="server" ID="txtoptionone" MaxLength="10" Width="70px" CssClass="TextBoxes"></asp:TextBox>
</div>
