# <xmod:CommandButton>
The CommandButton tag renders as a push-button at run-time. It is used to execute data commands in another template within the module instance. For instance, if you had two templates, you might put a CommandButton in template #1 to pass a parameter to the <ListdataSource> of template #2, causing that template to re-load with the new result set.

# Remarks
Usage: Command controls are used to execute a pre-defined data command in another template. You can execute multiple commands within a single control. Commands are defined in the
<Command>child tags. Each command will be executed in sequence, but please note that there is no transaction assumed. If a command fails, all those that went before it will NOT be rolled back.For each command, you identify the template whose datasource you want to execute by specifying the template's ID in the "target" attribute. If you set the "type" attribute to List, the
<ListDataSource>will be executed and passed any parameters you specify via<Parameter>child tags.BackColor: Color of the background of the control.
BorderColor: Color of the border around the control.
BorderStyle: Style of the border around the control.
BorderWidth: Width of the border around the control, specified in units
CssClass: Name of the Cascading Style Sheets (CSS) class used to style this control.
Font Properties: A series of attributes such as font-bold, font-size, etc. that allow you to control how the text in the control is displayed. More
ForeColor: Sets the foreground color (typically the color of the text) of the control.
Height: Height of the control, specified in units.
OnClientClick: Should you wish to perform some action on the client when the control is clicked, add your Javascript function call or script in this attribute. If your script returns false the control will not perform its normal processing. If you return true then the control will perform its normal processing.
Redirect: Enables you to redirect the user to an alternative URL after the button is clicked. The redirection occurs after any form processes initiated by the button click completes.
RedirectMethod: Determines the HTTP method by which the user is redirected: "Get" or "Post".
Style: Same as the HTML style attribute. It allows you to apply CSS styling to the control (e.g.
color: red; border: solid 1px black;).Text: The caption that will be displayed on the control.
ToolTip: In browsers that support it, sets the text to display when the mouse pointer hovers over the control.
Visible: Determines if the control is visible (true) or hidden (false).
Width: Width of the control in units.
