adding linkbuttons at run time?

[bazzer]

hey,
i have an ASP.NET webform linking to a microsoft access database. at
runtime, i need the application to add x linkbuttons to a panel. x will
be the number of entries under a certain field in one of the tables
from the database, which can vary each time.

i just cant get my mind around how to go about doing this. could anyone
point me in the right direction or even just explain to me what i need
to do?

thanks,

Hi Bazzar, it's pretty straight forward. Just create some LinkButtons
inside your Page_Load event and add these to the Panel's Controls
collection.

You must remember to add them even if it's a page PostBack otherwise
the Command events won't get fired when you click an item.

I've used the CommandArgument so set an ID as you'll need to know
which one was fired and they all go to the same event handler
button_Command:

private void Page_Load(object sender, System.EventArgs e)
{
int numLinks = 10;
for(int i = 0; i < numLinks; i++)
{
LinkButton button = new LinkButton();
button.Command += new CommandEventHandler(button_Command);
button.CommandArgument = i.ToString();
button.Text = "Entry " + i;
Panel1.Controls.Add(button);
Panel1.Controls.Add(new LiteralControl("<br/>"));
}
}

private void button_Command(object sender, CommandEventArgs e)
{

}

Bazzer,

I have a few examples of loading up controls dynamically on my website:

Use the search box there to search for dynamic controls and take a look at
the examples. If you have any questions after that feel free to email me.
