View 3 RepliesI'm using a searchoption on my website. (language = VB)
The user can choose a searchcriteria out of a dropdownlist (Artist name, Description, Price, Genre, Type) . If the user selects one of the options in the dropdownlist the correct textboxes are shown.
For example: if the user selects Price he gets two textboxes (one for the min price and one for the max price) if the user selects Artist Name he gets one textbox
The dropdownlist and the textboxes are put into an updatepanel. The searchbutton is outside the updatepanel.
Now for the problem:
If the user doesn't fill in a textbox and presses the searchbutton, the backcolor of that empty textbox should be turned red. The searchbutton is set as a trigger and the panel is updated on the buttonclick, but the colors don't show.
In the clickevent of the button I've said the following code:
If txtCriteria.text = "" then
txtCriteria.backcolor = Red
Else
txtCriteria.backcolor = White
End if
Quite a simple piece of code. This works if I remove the updatepanel from my page, but I'd like to keep the updatepanel because it's really nice :p.
i am trying to set the backcolor of textbox inside UpdatePanel but it don't seems to work...
how can i do that?
I am binding the textbox backcolor from database. My code is looking like this
<asp:TextBox ID="TextBox1" runat="server" BackColor='<%#(Eval("Colour")) %>' Enabled="False" Width="18px" BorderWidth="0px"></asp:TextBox>
When i execute this page i am getting the following error.
Specified cast is not valid. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.InvalidCastException: Specified cast is not valid.
I have an ASP.net page with two textboxes where the user types in input. I applied a requiredfieldvalidator to both textboxes as well. However, I also want the textboxes to change to a backcolor of red if the form is invalid when the user clicks the button to submit the input. I tried this code below in tthe button click event, but doesnt work...
If Page.IsValid = False Then
txtCosts.BackColor = Drawing.Color.Red
txtRevenue.BackColor = Drawing.Color.Red
End If
How else can I change the Backcolor of the textboxes when the input is invalid.......

I have a problem with regular expression because I want to validate a textbox and I want that mark the error text when the textbox be empty.
View 1 RepliesI am using regex for server side validations.
I am facing a problem with regex. I want to check for sepecial characters like ><*&()%$@!~+...
I need to filter these special charecters...but the problem is in my 10 textboxes there only 3 are required...
I can submit the form without entering anything...but my regex is not allowing me to submit the form without giving a space from keyboard...
I just want to check for special charecters and empty textbox without giving a spacebar...
I just check these sites(http://regexlib.com/ and http://www.regular-expressions.info/) and read some documentation on regex...its kind of confusing....
Here is my regex for Middlename: ^[a-zA-Z''-'s]|[ ]{1,40}$ its worked but its not correct....then I changed it to ^[a-zA-Z''-'sd*]{1,40}$ this also not taking emptytextbox without giving a space...
My Goal:
In most of the textboxes I need to allow only numbers and - # _ in some textboxes....
For Address: need to allow alphabets and numbers and #-_' "
City: numbers and alphabets no special chars...
Main problem is I can write regex for most of these stuff but need to all textboxes without entering anything (empty textboxes).My work got stoped due to this.

I worked in viewstate stuff and enabled it for the textbox and page, but with no results.
I have a textbox named txtOrderDate on my web page. I have a VB.net subroutine that saves various textboxes from my web page to my SQL table using a stored procedure. If a valid date is entered into txtDate, then my save works correctly. I have a column named OrderDate in my table. This is the column I am saving txtOrderDate to. OrderDate is defined as a date column and null is allowed.
But if txtorderDate is blank, my subroutine bombs saying cannot convert string to date. I tried various things like making the value of txtDate = DBNull.value if blank but nothing works. Seems like there would be an easy way to do this.
I want confirm button extender to pop up when Particular TextBox is empty.

I have this code to check if the textbox is empty on lost focus. Setting IsAutoPostBack = True and using TexTChanged.
Code:
if (string.IsNullOrEmpty(TextBox1.Text))
{

DateTime dateformat;
if (DateTime.TryParseExact(TxtDate.Text, "dd-MMM-yyyy", null, DateTimeStyles.None, out dateformat) == false)
{
lblErrMsg.Text = "Enter valid Txtdate";
return;
}
by using above query i am alert the if date entry format wrong. it is working fine but when ever if user not enter any date in TxtDate.Text then no need to alert just save datetime.minvalue. how to do it.
I want That validate the textbox so this no be empty I put that
"[ws]{1,50}"
But I want that the error mark when the textbox be empty.
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>
I need to validate textbox is not empty if check box is checked.
