If you want to get Last record from the dataset then you can go this way

int LastIndex=demodataset.Tables(0).Rows.Count - 1

Now you can get last record from the dataset using this lastindex

id = demodataset.Tables(0).rows(LastIndex)("id")

I am trying to navigate to another page with the help of a button.
I used onClick="window.location='http://localhost/adbintranet/index/GoldDriveCustInfo.aspx'"

When i compile i get an error that reads:
Compiler Error Message: BC30456: 'window' is not a member of 'ASP.GoldDrive_aspx'.

I have tried different onClick methods but still get the BC30456.

Please help.

If you are writing the code Buttonclick event, it should be Response.Redirect("GoldDriveCustInfo.aspx");

window.location is javascript code. You cannot call the method directly.

However you can add like this:

//In Design page
function OpenWindow()
{
window.open(url,windowname);
}

Button1.attributes.add("OnClick","OpenWindow()");

Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.

Hi there,

I have an image map of a keyboard and I need to map hotspots on to each key to display in the display box. Anyone know of an easy way to do this (ie just outline the region) or do I have to go through and work it out manually?

Thanks

Returning a Notification or Error Message to the User

I'm looking for a clean way to return a notification message to the user. For example, if I have a forum and the user adds a post to the forum I return something like "the post was added successfully". Now, in order to do this, I usually create three panels, one for the controls needed to add the post and another one for the notification message in case of success and the third one is an error message in case something goes wrong. When the user clicks the "Add Post" button I hide the controls panel and show the panel that contains the notification message (if the post was added successfully) or show the panel that contains the error message (if the add post failed). I wonder if there's a better way to do that. I thought about two alternatives and I would like to have some feedback from you. The first alternative is to use Server.Transfer(), ie. when the user clicks the "Add Post" button, the request is transferred to another page that contains the notification message (or to a page that contains an error message if the add post failed). The other idea is by using ContentPlaceHolder controls. I always use a masterpage with one ContentPlaceHolder control for page contents, I was wondering whether it's possible to clear all contents from the ContentPlaceHolder control in a content page and just add the success notification or error message.

Do you have alternatives other than those two? Which approach of the three (if any) do you think is better? And what do of the advantages and disadvantages of each of them?

Your feedback is really appreciated ..

You are assigning the ids in a loop. So same id will repeat multiple times. You need to use random unique value as id.

foreach (DataRow row in dataSetselectactivities.Tables[0].Rows)
{
      lb = new Label();
      tb = new TextBox();
      tb.Id = Guid.NewGuid().ToString();
      lb.Text = "<br />" + row["field"].ToString() + " ";
      tb.Text =   row["field"].ToString();
      RequiredFieldValidator reqv = new RequiredFieldValidator();
      reqv.ControlToValidate = tb.Id;
      reqv.ErrorMessage = "Err_Msg";
      TextBoxesHere.Controls.Add(lb);
      TextBoxesHere.Controls.Add(tb);
      TextBoxesHere.Controls.Add(reqv);
}

I used GUID as an example. You may use any unique value there.

Thanks for that.
The final thing is to loop all the textboxes I have just added and add the value from them into the database. Is it possible to loop controls like:

foreach (control in TextBoxesHere) something like that, or do I have to put them in an array?

cheers!

This should work

foreach (Control control in this.form1.Controls) {
    if (control is TextBox) {
         TextBox textBox = control as TextBox;
         // use textBox here
     }
}

Im getting an input string error when I try to add the fields to the database.
I thnik it has something to do with the following parameter:

cmd_update.Parameters.Add(new SqlParameter("@field", SqlDbType.Int));
cmd_update.Parameters["@activity_order"].Value = tb.Text;

now tb.text is supposed to be the value from the dynamically created control in my page(the code to create the controls is in the third post on this thread) but its not working

any help on this would be great

thanks
