asp.net Calling a server side function from client side

[Kleryk]

I dynamically create buttons on the fly based on how many objects are in the database, but because of this they can only be html buttons <asp: does not work. Now i need to run a function in my codebehind file any ideas how to do this?

Atm i have:
<input type="submit\" name="GanttButton" value="Button" runat="Server" onclick="Select_Node" id="GanttButton" />

public void Select_Node(object sender, CommandEventArgs e)
{
....
}

but this does not seem to ever fire :S
do i need to create a javascript function on client side which then calls the function on the server?

You need to create the button as controls. Writing "<asp" to the response stream does not send it to the pre-processor or anything.

Lets say you have a <div> (that would be <asp: pannel>) with something like this in your aspx file:
<asp: Pannel runat="server" ID="pnButtonsGoHere">
</asp: Pannel>

now in your code, where you create the buttons you would have something like this:

Button mybt;
for (int i = 0; i < NumButtons; i++)
{
mybt = new Button();
mybt.Tex = "The Displayed Text";
mybt.ID = "bt" + i.ToString();
mybt.Click += new EventHandler(MyButtonHandler);
pnButtonsGoHere.Controls.Add(mybt);
}

Now you will notice I used the same eventhandler for every button. You will need to create that function and inside do like a SWITCH statement on the ID or Text fields. Give that a try.

PS: All the like CSS/STYLE properties can be set for all those buttons, just play around with the members of the control
