Hello,
I am creating a Poll system and I need to check if a user has already voted.
What should be the best way to do this?
1. Should I save the user IP along with its vote in the database?
But does not some users IP change each time they access the internet?
2. Should I place a cookie in after the user voted?
Well, any help will be great.
Thanks,
Miguel

If this is for authenticated users only, then you could always associate the vote and the users. If everybody can vote, then you should use cookies.

Hey every one.
I have a webpage with server-side controls that are validated on the server side, however this is costly so i would like to perform some of the validation on the client side (using javascript).
How do i go about performing the validation on the client side.
I have tried changing the control to for example but the page doesnt load and i am informed this is an invalid attribute.
Is this possible and if so how do i go about it?
Thanks
Dan

Use the ASP.NET validator controls.

The other best way can be use Java Script. You can
a) Create Js files
b) And Add JS to control by using Attributes.ADD property. FYR i am attaching one sample code
btnSubmit.Attributes.Add('OnClick',"javascript return MyMsg();")
And here is JS
function MyMsg()
{
Alert("I am fine");
}
Thanks

Please don't repost. You posted this 13 hours before this one. The people who help on this site will get to you if they can, and if they think they can help.
Your question isn't clear, and this doesn't help.

I'm creating a .NET crystal report sales report that lists the total # of each item sold and the percentage of total sales that the item contributed towards however, before I can calculate the percentage for each row, I need to know the total qty of the report, which I don't know how to retrieve.
So a sample report of 500 items sold may look like this:
-----------------------------------------------------------
Category | Qty Sold | Percentage
-----------------------------------------------------------
Electronics | 200 | 40%
Books | 100 | 20%
Movies | 150 | 30%
Games | 50 | 10%
-----------------------------------------------------------
Total | 500 | 100%
-----------------------------------------------------------
How can I calculate a percentage for something like this?
Thanks.

i've been working with ASP.NET for the last 2 years. But the problem is that i've never had any strategy for designing. I'm the only ASP.NET programmer in my office and b/c of that i never bothered to follow any of the design framework. Eventhough i know uml & OOAD, i would just create a few UML diagrams and then jump right into programming. I was wondering if anybody could recommend any books or articles that would enlighten me on how to create an ASP.net application by walking through each of the design, analysis & testing steps. Please help me with your advise. Would greatly appreciate your help.

"Someone has asked me to put this question in asp.net Forum. So, please make sure this is NOT DOUBLE Posting"
Hi all. I have a textbox in which i will add "Comments" on aspx page along with an Add button. On this page , i have a gridview as well. The problem is,
When i enter value in TEXTBOX and press ADD button, the value in textbox should have to be populated in Gridview without PAGE REFRESH. Please make sure the current scenario.
I have a table ABC with a column Comments. I have to pull Data from ABC table in Gridview. so, when i add value in Textbox and press add button, basically it will save first in ABC table and then refresh the gridview behind the scene. Please let me know How I can achieve it. Thanks for your consideration

Your best bet would be to use some AJAX framework. We have purchased the telerik controls, so that is a piece of cake. You could probably accomplish this with ASPNet AJAX which is free.

You can implement ICallbackEventHandler interface in your webpage and use client-callbacks to call the server when the Add button is pushed sending the text to be added as a param.
You'll find the details on how to accomplish that here: http://msdn2.microsoft.com/en-US/library/system.web.ui.icallbackeventhandler.aspx
Then, on the server side in the RaiseCallbackEvent method, add the text to the grid and render the grid to a StringWriter like this:
StringWriter stringWriter = new StringWriter(CultureInfo.InvariantCulture);
HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);
yourGrid.RenderControl(htmlWriter);
htmlWriter.Flush();
htmlWriter.Close();
string result = stringWriter.ToString();
You have to send back the result to the client side where you have to replace the outerHTML of the grid with the data you recive from the server. Your javascript function that recives the callback result and does the replacement should look something like this:
function __onServerCallback(result, gridID)
{
else if (result.length)
{
// set the resulted data to the grid
var grid = document.getElementById(gridID);
grid.outerHTML = result;
}
}
I hope this will help and I'm sure you will find good articles related to this subject on codeproject. Just search for ICallbackEventHandler.

How can we know that Excel is installed on a PC using ASP.NET 2.0??

In ASP.NET 2.0, you can add a reference to the "Microsoft Office 11.0 Control Library" dll.
There may be something within that object that can achieve what you're looking to do. The only catch is I believe it's only compatible with ms office 2003 or higher.

Hello
I am new with asp 2.0.
I created a question.aspx page with a formview control. Then I inserted a TextBox1 in the formview Item Template.
My Problem:
How can I write a Value to the TextBox1 in the Formview Item Template?
If I write the following code in the question.aspx.vb page:
Partial Class question
Inherits System.Web.UI.Page
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
TextBox1.text = "hello"
End Sub
End Class
then I'm receiving an error message: TextBox1 is not declare.
If I put the TextBox1 Control outside the formview then I can write a value in the TextBox1.
Do you have a tip or could you recommend me some tutorials to solve the problem?
plz help

I have never used the formview control. But I guess it would be
dim txt as textbox = formview1.findcontrol("TextBox1")
|
|
|
|

It solve the problem. But I do not know , why it is necessary.
Thank you.
