Hi,

We often get the requirement to set a default view based on some criteria (Ex – Could be based on logged in user role, etc…). We can achieve this using a Plug-in.

Little insight :-

• When you click on an entity (i.e., ‘Contacts’ in my sample) in CRM application, In the background a “RetreieveMultiple” method call  happens on “savedquery” entity.

• “savedquery” is a system entity in CRM which stores the meta data of all the views in the system

Plug-in Logic :-

• We register a Plug-in for the RetreieveMultiple message on the savedquery entity to be executed in the post stage
• From “Outputparameters” fetch the “BusinessEntityCollection” (i.e., Views of particular entity)
• Loop through the views and set “isdefault” property to “true” for the desired view

–          Below is the sample code

public void Execute(IServiceProvider serviceProvider)

{

this.context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

var serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));

var service = serviceFactory.CreateOrganizationService(this.context.UserId);

if (this.context.InputParameters.Contains(“Query”) && this.context.InputParameters[“Query”] is QueryExpression && this.context.Stage == 40){

var qe = (QueryExpression)this.context.InputParameters[“Query”];

if (qe.Criteria != null) {

var condition = (ConditionExpression)qe.Criteria.Conditions[1];

// “Type code” of entity you want default views ( Object type code of ‘contact’ is 2)

//  Refer Useful article on how to get “Object Type Code”

if (condition.Values[0].Equals(2)) {

// Name of the view you want to set as Default

string ourDefaultView = “My custom view – Contacts”;

if (!string.IsNullOrEmpty(ourDefaultView)){

var collection = (EntityCollection)this.context.OutputParameters[“BusinessEntityCollection”];

collection = ChangeViewCollection(ourDefaultView, collection);

this.context.OutputParameters[“BusinessEntityCollection”] = collection;

}

}

}}}

/// <summary>

/// Setting IsDefault property of views

/// </summary>

private EntityCollection ChangeViewCollection(string ourDefaultViewName, EntityCollection records){

foreach (Entity record in records.Entities){

string viewName = (string)record[“name”];

if (viewName.Equals(ourDefaultViewName)){

record[“isdefault”] = new bool();

record[“isdefault”] = true;

}

else {

record[“isdefault”] = new bool();

record[“isdefault”] = false;

}

}

return records;

}

Plug-in Registration Steps :-

Message Name – RetrieveMultiple

Entity – SavedQuery

Stage – post

• Register the assembly & Refresh the CRM application
