Hello

I forgot to mention that it was ImageButton and not Button, I used coordiantes to solve it.

However the answer you gave was very tricky and thanks for that. As you said none of the articles mention that. So I gave the highest rating Smile | :)

Selective validation?

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 can set the validation group so the signup fields don't trigger the validation for the comment field

You need to create the ValidationGroup for it. RequiredFieldValidator for txtEmailAddress , txtEmailAddress and btnSignUp should be under same validation group. Big Grin | :-D

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. Smile | :)

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"];
       //Read data 
        string Name= dt1.Rows[0]["Name"].ToString(); 

   }

This is an sample example, Hope this will help you Big Grin | :-D

Hello Is there a way to retrieve text from datalist

thanks alot

Abhijit Jana8-Aug-09 10:46

Re: retrieving text from datalist

8-Aug-09 10:46

yes.
You can use FindControl to identify any column and get the value for that column.

Control  myControl= (Control  )e.Item.FindControl("ControlName");

For future Reference,
