Well, this is trivial with a gridview, all the stuff you need, is built in. What have you done so far ? Written any code ? Referred to any books ? done any google searches ?

i have to check it on a sample page with 2 text box plus 1 gridview. Code is as :
Partial Class Default2
Inherits System.Web.UI.Page
Private dsSelect As New DataSet
Private Sub CreateGridTable()
dsSelect.Tables.Add("Region")
dsSelect.Tables(0).Columns.Add("RegionID")
dsSelect.Tables(0).Columns.Add("RegionDescription")
End Sub
Protected Sub TextBox2_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged
Dim vCount As New Integer
If dsSelect.Tables.Count = 0 Then
CreateGridTable()
Me.GridView1.DataSource = dsSelect.Tables(0)
End If
vCount = dsSelect.Tables(0).Rows.Count
dsSelect.Tables(0).Rows.Add()
dsSelect.Tables(0).Rows(vCount).Item("RegionID") = Me.TextBox1.Text
dsSelect.Tables(0).Rows(vCount).Item("RegionDescription") = Me.TextBox2.Text
Me.GridView1.DataSource = dsSelect.Tables(0)
Me.GridView1.DataBind()
End Sub
End Class

Your code is illegible because none of your variable names are meaningful. However, reading it, I really can't work out why you expect it to work. dsSelect is a member, and all it contains, is the text you entered. So, your gridview1 will always contain one item - the item you just entered. Seems stupid to me. What do you expect it to do ?

Because as i deploy my simple web application in which i have only one web form and that cs file doesn"t have any code and created an msi (windows installer) and i installed that msi in other system and in that system if access my web application i got an error like...
Exception Details: System.Security.SecurityException: Requested registry access is not allowed
Stack Trace:
[SecurityException: Requested registry access is not allowed.]
System.ThrowHelper.ThrowSecurityException(ExceptionResource resource) +51
Microsoft.Win32.RegistryKey.OpenSubKey(String name, Boolean writable) +7460233
System.Security.Cryptography.Utils.get_FipsAlgorithmPolicy() +239
System.Security.Cryptography.MD5CryptoServiceProvider..ctor() +25
System.Web.Compilation.AssemblyBuilder.AddChecksumPragma(BuildProvider buildProvider, CodeCompileUnit compileUnit) +8569699

System.Web.Compilation.BaseTemplateBuildProvider.GenerateCode(AssemblyBuilder assemblyBuilder) +462
System.Web.Compilation.AssemblyBuilder.AddBuildProvider(BuildProvider buildProvider) +99
So i guess by default aspnet account access registry which is not allowable......

Why would an ASP.NET app write to the registry ? Why not use a config file to store your data ?

Hi all,
In my application, i have one requirement that i want to show popup type reminder on particular time which is set by user. This is call center type application in which executive set the reminder to call on particular time and all his reminder message and time are inserted into the database and to show popup, it will fetch the reminder data from the database.
I have one clue to implement it, but performence wise its not good to implement it. So Is there any way to implement it???????????
Thanks in advance...

You can set a timeout in javascript, so you can inject the code to do that, with the appropriate timeout value based on the users timezone ( which you can also find with js, but that's a little tricky, if you know their timezone, that would make it a lot easier ). So, the page you send, can be set with a timer to show that message, without having to refresh or use ajax.

Hi, Thanks for replying...
Yes, You are correct..and now see this...
I make one function in javascript, just for testing
function startTime()
{
var today=new Date()
var h=today.getHours()
var m=today.getMinutes()
var s=today.getSeconds()
t=setTimeout('startTime()',1000)
}
In the above code startTime function call recursively bcs i have to check the datetime from the database which is there in the page. so it will run after every 1 minuite and it will run on every client computer.
so can u think performence wise it is suitable??
And yes one more thing Here JQuery can help me? I want yr suggesion.
Thanks again...

It's called code. You build a data layer to support storing the details of posts, and forums if you want more than one. Then you build the UI that allows you to add and display records.

Hi,
When i try to upload an excel file that has a date column, there is a issue in the system language. That is, when i tried my application in my system which has regional settings (System Language:English-US;Programs that run non-unicode format: English-US)and it was working perfectly. The datas got uploaded.
But when i tried in another machine that has the system settings (System Language:English-UK;Programs that run non-unicode format: English-UK), this threw me an error "Invalid date format in excel".
Help me out.
Thanks in advance.

You mean reusing the DataGridView?
If so yes you can, just call the Clear method before assigning the datasource second time
OR set the datasoruce to null.
Be careful, there is no Undo Button(Ctrl+Z) in life.

Please don't use txtspeak, it makes you look like a moron.
But, given how trivial your question is, and how easy it would be to test if this will work ( or just to put two styled grids on a form and only show the selected one ), perhaps first impressions are correct.

Why would you want to ? Why would you ask this and not just try it ?
Yes, if they have the same columns or if you have the columns auto generated, then of course you can.

ASALAMOALEKUM,
I am working with ASP.NET and c#
i have a chatting website.
i have two pages:
page1: names of all the chat rooms available
page2: a chatroom (for chatting)
i have use database to store chat and then by using ajax timer i have updated the displaying textbox with chat from database... for each chat room, it stores chat in the database w.r.t to its roomid.
i have made a class "chat" which contains static member ROOM_ID.
when user click on any room_name (from page1), the respective roomid is stored in the static member ROOM_ID and direct to page2 where all the working is done on the basis of the ROOM_ID.
as per scenerio i needed to open more than one chat room at a time so i have used OnClientClick event to target to new browser window when clicks on the room name from page1.
now i am facing two probelms...
1st:
i have run my application on browser say "A", for the first time when i click on any roomname, it opens the application in new browser say "B" but not with the page2(chat area for that room) but a LOGIN page of my website and when i log on to it it directs to the HOME page instead of directing to the page2.. and then when i again click on the roomname of page1 on "A" or "B" now it opens the new browser window say "C" with requested page2. (but for this i have to login to that page which was for the first time opened in new browser window "B" otherwise browser "C" also initiate with LOGIN page)..
how to avoid this LOGIN page ??
2nd:
Its a major problem, i dont know whether to have some different settings while working with different browsers incase of handling database too.
well...issue is :
i have opened a chatroom1 in browser"A" .. when i am working with only one chatroom its fine
now when i open a chatroom2 in new browser "B",, with the loading of this chatroom2 the chatroom at browser "A" tends to adopt the values of chatroom2.. that is both the browsers show the chat msgs of chatroom2...
how to handle thisss... ??
i know there must be any soln to thisss.. else having individual form for each chatroom is totally wastage and not a good practice because rooms are created and deleted by the user !
please reply!
thanks,
Regards.

Sounds like your design is broken. For a start, a static variable is obviously going to be the same for all your pages, and in fact, I'd have expected it to be the same for all users, have you tested with two lots of users running at once in different rooms ? It sounds to me like your code has a lot of issues stemming from poor design.
