There are three properties of type string from the server-side API which are assigned the name of a client-side javascript function as a parameter. By default this is a standard function but you can add "if" clauses in its body. The table below contains description and examples of using these properties:
|
Property |
Description |
|
OnClientPageLoad |
Gets or sets the client function to be called when a page is loaded in a Telerik RadWindow dialog. As an argument it receives a reference to the particular window to be shown.
Example
| aspx/ascx |
 Copy Code |
|
<rad:RadWindowManager
id= "RadWindowManager1"
runat= "server"
OnClientPageLoad = "OnClientPageLoad"
>
<windows>
<rad:RadWindow id="UserListDialog"
OpenerElementId = "<%# ServerButton.ClientID %>"
OffsetElementId = "InfoDiv"
Left= "150px"
Modal = "true"
Runat= "server"
Width= "250px"
Height= "400px"
Title= "User List Dialog"
NavigateUrl= "./Dialog.aspx">
</rad:RadWindow>
</windows>
</rad:RadWindowManager> |
| Javascript |
Copy Code |
|
function OnClientPageLoad(radWindow)
{
alert (radWindow.Name + " has finished loading");
} |
|
|
OnClientShow |
Gets or sets the client function to be called when a window is being shown. As an argument it receives a reference to the particular window to be shown. Good for setting an argument to the window.
Example
| aspx/ascx |
Copy Code |
|
<rad:RadWindowManager
id= "RadWindowManager1"
runat= "server"
OnClientShow = "OnClientShow"
>
<windows>
<rad:RadWindow id="UserListDialog"
OpenerElementId = "<%# ServerButton.ClientID %>"
OffsetElementId = "InfoDiv"
Left= "150px"
Modal = "true"
Runat= "server"
Width= "250px"
Height= "400px"
Title= "User List Dialog"
NavigateUrl= "./Dialog.aspx">
</rad:RadWindow>
</windows>
</rad:RadWindowManager> |
| Javascript |
Copy Code |
|
/* Called when a window is being shown. Good for
//setting an argument to the window */
function OnClientShow(radWindow)
{
alert (radWindow.Name + " is being shown");
var arg = new Object();
//An argument can be anything - string, number, object.
//If it is an object, various properties can be
//set for carrying multiple information
arg.SomeValue = "Value1";
//Set the argument object to the radWindow
radWindow.Argument = arg;
} |
|
|
OnClientClose |
Gets or sets the client function to be called when a window is being closed. As an argument it receives a reference to the particular window to be closed.
Good for doing cleanup work.
Example
| aspx/ascx |
Copy Code |
|
<rad:RadWindowManager
id= "RadWindowManager1"
runat= "server"
OnClientClose = "OnClientClose"
>
<windows>
<rad:RadWindow id="UserListDialog"
OpenerElementId = "<%# ServerButton.ClientID %>"
OffsetElementId = "InfoDiv"
Left= "150px"
Modal = "true"
Runat= "server"
Width= "250px"
Height= "400px"
Title= "User List Dialog"
NavigateUrl= "./Dialog.aspx">
</rad:RadWindow>
</windows>
</rad:RadWindowManager> |
| Javascript |
Copy Code |
|
/* Called when a window is being closed. */
function OnClientClose(radWindow)
{
alert (radWindow.Name + " is being closed");
} |
|
|
ClientCallBackFunction |
Gets or sets the client function to be automatically called when a rad window is closed. The difference to the OnClientClose event is that a second argument is provided - the return value (if any) from the dialog.
Can also be called explicitly from within a rad window (good for scenarios where dialog should return values to the opening page multiple times). This function will be called only if there is a returned argument from the content page.
Example
| aspx/ascx |
Copy Code |
|
<rad:RadWindowManager
id= "RadWindowManager1"
runat= "server"
ClientCallBackFunction= "CallBackFunction"
>
<windows>
<rad:RadWindow id="UserListDialog"
OpenerElementId = "<%# ServerButton.ClientID %>"
OffsetElementId = "InfoDiv"
Left= "150px"
Modal = "true"
Runat= "server"
Width= "250px"
Height= "400px"
Title= "User List Dialog"
NavigateUrl= "./Dialog.aspx">
</rad:RadWindow>
</windows>
</rad:RadWindowManager> |
| Javascript |
Copy Code |
|
/* Can be called from within a rad window */
function CallBackFunction(radWindow, returnValue)
{
//Do something with the return value!
alert (radWindow.Name + " CallBackFunction is called with
returnValue=" + returnValue);
} |
