Text="click me"
OnCallback="buttonCallback"
ActiveControl.CallbackOptions="options"
/>
<com:TCallbackOptions
ID="options"
ClientSide.OnLoading="$('callback_status2').hide(); new Effect.BlindDown('callback_status', { duration: 1 });"
ClientSide.OnComplete="new Effect.BlindUp('callback_status', { duration: 1 }); $('callback_status2').show();"

<div id="callback_status" style="display:none;">please wait 5 seconds for the callback to complete...</div>
<div id="callback_status2" style="display:none;">callback completed!</div>

<tr><td class="samplenote">
Same example as before, but this time interacting with another Prado control:
</td><td class="sampleaction">
<com:TActiveButton
Text="click me"
OnCallback="buttonCallback"
ActiveControl.CallbackOptions="options2"
/>
<com:TCallbackOptions
ID="options2"
ClientSide.OnLoading="$('<%= $this->label1->ClientID %>').innerHTML='please wait 5 seconds for the callback to complete....';"

/>
<br/><com:TLabel ID="label1" ForeColor="Red" Text="waiting for button click.." />
</td></tr>
<tr><td class="samplenote">
The same TCallbackOptions can be shared among different controls, even of different types:

<com:TActiveButton
Text="simple button"
OnCallback="buttonCallback"
ActiveControl.CallbackOptions="options3"
/>
<br/><com:TActiveCheckBox
Text="simple checkbox"

ActiveControl.CallbackOptions="options3"
/>
<br/><com:TActiveDropDownList
OnCallback="buttonCallback"
ActiveControl.CallbackOptions="options3"
>
<com:TListItem Value="value 1" Text="item 1" />
<com:TListItem Value="value 2" Text="item 2" Selected="true" />
<com:TListItem Value="value 3" Text="item 3" />
<com:TListItem Value="value 4" Text="item 4" />
</com:TActiveDropDownList>
<br/><com:TLabel ID="label2" ForeColor="Red" Text="waiting for any control to callback.." />
<com:TCallbackOptions
ID="options3"
ClientSide.OnLoading="$('<%= $this->label2->ClientID %>').innerHTML='please wait 5 seconds for the callback to complete....';"
ClientSide.OnComplete="$('<%= $this->label2->ClientID %>').innerHTML='callback completed!';"
