Regular Expression Validator - ASP.NET Discussion Boards

In my aspx page there is some heading that comes at runtime and a gridview.
How should i export both the details in the excel.

If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

at the front level every thing is fine .But i am unable to export a text(heading) in excel sheet.
Otherwise , the gridview contents are getting exported in the excel , with the help of the link that u provided.

Hi Friends,
I have one textbox control which i will type some characters and then i will press search button a pop up window will appear i will select the name from the pop up window and enter means the values are displaying in the textboxes till now no problem,when i select the value from pop up window the values will display in parent window and another textboxes which i will have ,displaying regular expression error message.Kindly tell me how to avoid the message.

Thanks & Regards
Senthil Kumar

Can the pop window prefill the textbox with sanitized data? If you are filling the textboxes automatically then what makes you to break your own rules and trying to fill it?

I see that there is some validation missing in the popup window rather than in the regular expression validator that fires in the parent window.

Complet news paper portal and every one hour need to display the update news.

If you want the site to autoupdate, you can use javascript to make the page auto refresh, or AJAX to make a call to refresh part of a page.

In a good design, the content and news items should be controlled and should not autoupdate since it would irritate users besides an undue load on the server.

However, you can have a simple news ticker which refreshes the messages. Have you checked out NDTV (http://www.ndtv.com/[^]) website?

All of this was clear in your last post, but if you want to clarify something, edit your post, don't post another.

Stop crop-dusting the forums with your same sh*t and junk. You were already suggested quite descriptively how to address and overcome the issues in your problem over here:

In code behind page
if i use this condition. Then it show an error ie Operator '>' cannot be applied to operands of type 'string' and 'string'

How to Solve this problem

if ( addrow51.Text > "12:59")
{
label1.Text = "Please Enter the Valid Time";
}

I know you've been told this before, but, read this[^]. The many levels on which this shows that you have no idea how C# works, are hard to fathom.

I know people like you don't want to learn, you want your job done for you. So, here goes.

1 - your variable naming is a disaster. Never use the default names. Especially if you 51 different variables that are all called addrow.
2 - like the error says, you can't use > to compare strings. It certainly isn't going to do what you're expecting. Are you generate validating this text to make sure it conforms to the format you're hoping for ? You need to do that first, then you need to turn this into a format such as datetime ( although not sure if you can make a datetime without a date, I'd be more inclined to use string.split and int.TryParse to work out what you were dealing with )

I suspect you have no idea what I just said. If so, it proves again that you need to read some basics before you write code that is ever going to be used by anyone, and if anyone is paying for your code, you are stealing from them.

I agree, and your post cracked my sh*t up, just had to throw some Aliens quote in there (use it or lose it!) Do you think we should even bother telling him/her about CompareTo or DateTime.TryParse/Parse, et al?

I dunno if DateTime.TryParse will work with just a time ? I tried to give a pretty straightforward answer, I think the best way to enforce this format, and to check the value, is to split the string and do an int.TryParse on the different values.

Even when I blast someone for utter laziness and cluelessness, I try to provide an answer they can use, if they are willing to read it.

TryParse does work with just a time, it defaults to the current system date.

So this works, although it seems a bit complex:

string userText = "12:59";
DateTime now = DateTime.Now;
DateTime checkTime = new DateTime(now.Year, now.Month, now.Day, 12, 59, 0); // assuming 12:59am
DateTime userTime = DateTime.MinValue;
DateTime.TryParse(userText, out userTime);
if (userTime > checkTime)
{
// Valid
}
else
{
// Invalid
}

OK, well, I guess he got his answer then Smile | :)

Thanks, I had no idea and I didn't like to do more work for an answer than the OP was willing to do for himself. But, it's good to know.
