Remarks
If this property is set to a value, the value is emitted into the registered client ECMAScript (JavaScript, JScript) for this control and the application uses the client value of this ECMAScript (JavaScript, JScript) to specify the callback function for the Asset Picker dialog box. This client callback function is called after the Asset Picker dialog box returns a value and the returned URL and default text are stored in any HTML elements specified by AssetUrlClientID and AssetTextClientID. This ClientCallback property is called whether the Asset Picker dialog box is opened by using an Asset Picker button or from ECMAScript (JavaScript, JScript) retrieved by the GetClientLaunchPickerReference method. If the AutoPostBack property is set to true, the AutoPostBack happens after the call to the ClientCallback function is complete.
The string for this property can be the name of an appropriate ECMAScript (JavaScript, JScript) function available in the page, a global variable with an appropriate function reference stored in it, or an explicitly defined anonymous ECMAScript (JavaScript, JScript) function string such as the following.
function(newAssetUrl, newAssetText, configObject, returnValue)
{
//Perform client side script operations with the new asset URL value
}
// Set the ECMAScript to perform after populating the text boxes with the returned values.assetSelector.ClientCallback = ScriptClientCallback;
Private Function [function](ByVal newAssetUrl As String, ByVal newAssetText As String, ByVal configObject As Object, ByVal returnValue As String) As String
'Perform client side script operations with the new asset URL value
End Function
' Set the ECMAScript to perform after populating the text boxes with the returned values.
