Update the Parent Silverlight Grid from the CRM form that is spawns.

We were working on the Silverlight REST Editor sample that is available in SDK.

We added a hyperlink to that grid that would open the CRM Contact form for the selected contact. This would allow users to check in further details of the contact. The users can also update the fields on the contact form there. Say the user edits the Phone on the Contact form instead of in the editable grid that we have presented them with… (users always tend to do what they are not supposed to do )

Now the issue raised was… after closing the CRM contact form, the changes made on the contact were not reflected in the grid. The user did not want to perform the search again to check the updated values…

How do we fix this…

1. Modify the Silverlight controls class and qualify it with the [ScriptableType] attribute.

[ScriptableType]
public partial class MainPage : UserControl
{

public MainPage( )
{
InitializeComponent( );

HtmlPage.RegisterScriptableObject("MainPage", this);

}

Register the control for access through script.

2. Next create qualify a method to be [ScriptableMember]

[ScriptableMember]
public void RefreshContactGrid( )
{
//Here write the code to rebind the Grid
}

Now we can access this method through jscript.

3. In the HTML page add a function to call the RefreshContractGrid method

function reloadContactGrid( ) {

try {
var control = document.getElementById("silverlightControl");
control.Content.MainPage.RefreshContactGrid( );
}
catch (e) {
alert(e.Description );
}
}

Silverlightcontrol refers to the object id of the silverlight control on the HTML page.
<object id="silverlightControl" data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">

And “MainPage” is the class name, which we have registered as Scriptable Object.

4. As we would like the grid to be auto-refreshed on the close of the CRM form. We need to write the code on the CRM form OnSave event to call the reloadContactGrid function of the HTML page. This function internally calls the Silverlight method that actually binds the grid once again and refreshes the datagrid.

function reloadParentGrid( ) {
try {

if (window.parent != null
&& window.parent.opener != null
&& window.parent.opener.document != null
&& window.parent.opener.document.nameProp != null
&& window.parent.opener.document.nameProp == "RESTContactEditor") {

window.parent.opener.reloadContactGrid( );

} //End of IF

} catch (e) { }
}

With these 4 steps you should be able to auto-refresh the grid after the user saves the CRM form that they opened from within the grid.
