Setting Z-index (Z-order in vb6) and position of control in ASP.NET

dear guys,

i have used the asp.net to write my application, and i use the code-behind scenario.
i dunno how to set the textbox, image,.. and others contols in the "code-behind". i only can set the position in the front interface part (i use the grid layout).
this is bcos i want to do graphic drap-and-drop of some image control by clicking the button.

thanks you for whoever provide suggestion or opinion.

When you drop a control on the page, a variable corresponding to that control is added to codebehind file. the name of that variable will be the ID of the control that you set in the design view. To manipulate that control's appearance etc you can access the properties through the variabl. For example, If you drop a text box control on the aspx page...

** aspx file ***
<asp:TextBox ID="myTextBox" Runat="server"></asp:TextBox>

* in code behind file (C#) **

protected TextBox myTextBox;

private method ChangeTextBoxWidth()
{
myTextBox.Size.Width = 30;
}

this is just an example on how you can modify the apeearance.
-------------------

If you want to add control dynanmically... then best would be to drop a PlaceholderControl on the page. Put it where you want your controls to appear. And then code behind, create a new instance of your control and add it to Controls collection to PlaceHoldercontrol.
