I'm developing a Webform that displays a newsletter. At the bottom the newsletter, there is a comment textbox to allow the user to post a comment. I have a RequiredFieldValidator attached to the comment box to prevent empty comments from being posted.
All is working fine but I'm trying to add a "Sign Up" function so the user can register their e-mail address to receive the newsletter in their inbox.
The "Sign Up" functionality consists of:
* txtEmailAddress,
* RequiredFieldValidator for txtEmailAddress
* btnSignUp
Now when btnSignUp is clicked, the RequiredFieldValidator for txtComments will not allow the page to postback!
I know an easy solution would be to redirect the user to another page for registering and set btnSignUp property: CauseValidation to false. I guess I'm too bull headed but I want to give the user the quick access of signing up on the newsletter page! Is there any way besides a lot of javascript to accomplish this?
Thanks,
Richard

You need to create the ValidationGroup for it. RequiredFieldValidator for txtEmailAddress , txtEmailAddress and btnSignUp should be under same validation group.

Try out ds.Tables[0].Rows.Count..(just check the syntax  )
|

|

could you say little bit clearly

I think, you can get the count of rows which you are looking for.
ds.Tables[0].Rows.Count would give you the count of rows.
Let me know if you are looking for something else.

which kind of table ? Are you talking about GridView or what ?

sorry wrongly sent
Table in a DataSet

Yes you can. Load the DataSet Table data in DataTable. Then you can read the data from each and every row based on row index.
DataSet Ds= LoadDataSet();
if (Ds.Tables["Table1"].Rows.Count>0)
{
DataTable dtable = new DataTable();
dtable = Ds.Tables["Table1"];
string Name= dt1.Rows[0]["Name"].ToString();
}
This is an sample example, Hope this will help you

Not like this i want to get the rowindex of particular row.see the code which i am trying to do that
DataRow[] row =dsphotos.Tables[0].Select("PHOTO_ID",Session["ID"].ToString());
int rowindex= dsphotos.Tables[0].Rows.IndexOf(row[0]);

So what's your question? You are fine with your implementation or you want something else.

You can't insert text without a control.  What DataList are you talking about?

Dear All,
I have a page holding data in data list. I created paging option for datalist with dynamic link buttons created during-page pre init event. It runs if(!Ispostback).
Then I hold number of pages in session in order not to connect to database in each page refresh.
Then I have dropdown list accorging to which the number of pages changes. So the number of link buttons also should change with selection.
However when I clicked on the button page-preinit creates the link buttons before the it handles click event, therefore creates the link buttons according to the number hold in session, in other words according to previous page number..
Here are the codes
protected void page_Preinit(object sender, EventArgs e)
{
if (!IsPostBack)
{
getpagecount("0","0","0"); // gets the page count form database.
}
else { lb_Count = int.Parse(Session["Page"].ToString()); } //gets the figure in the session.
for (int i = 1; i <= lb_Count; i++)
{
LinkButton bottomLink = new LinkButton();
LiteralControl bottomLiteral = new LiteralControl(" ");
bottomLink.Text = i.ToString();
pnlBottom.Controls.Add(bottomLink);
pnlBottom.Controls.Add(bottomLiteral);
bottomLink.Click += new EventHandler(this.changeLink);
}
if (con!=null && con.State == ConnectionState.Open)
{
con.Close();
cmd.Dispose();
}
}
HERE IS THE CLICKED EVENT
protected void btnYemekler_Click(object sender, ImageClickEventArgs e)
{
//HERE, THE PAGE NUMBER IN SESSION CHANGES BUT THE LINK BUTTOS ARE ALREADY CREATED.
getpagecount(DlAscilar.SelectedValue.ToString(),
DlMutfaklar.SelectedValue.ToString(), DlBolgeler.SelectedValue.ToString());
doldur(DlAscilar.SelectedValue.ToString(),
DlMutfaklar.SelectedValue.ToString(), DlBolgeler.SelectedValue.ToString());
dlListe_Doldur(0);
}
WHAT CAN I DO TO HANDLE THIS PROBLEM.
THANKS IN ADVANCE

My answer may/may not be dirty, but that would work.
1. Place a Server-Side HiddenField in the *.aspx file.
2. Handle the OnClientClick event (JavaScript) of the Button.
3. OnClientClick you have to set the page number or whatever data you want into the HiddenField.
4. After the OnClientClick event, Button's Click process will start.
5. Now in your Page_PreInit get the values of the HiddenField and continue your routine process.
6. Here you can get rid of Session object.
Let me know if you have questions. Please mark it as answer if it helps you.
