How to Hide the Views in CRM 4.0 using plugin

This will work for an Account.............It will hide the inactive accounts from the view.

Same code will work for Contacts if you replace otc1=2 & Inactive Accounts to Inactive Contacts.

Code:--------------------------------

int otc1 = 1;

//StringCollection sc1 = new StringCollection();

//sc1.Add("Inactive Accounts");

//_hideViews.Add(otc1, sc1);

if (!(context.MessageName == MessageName.RetrieveMultiple && context.PrimaryEntityName == EntityName.savedquery.ToString() && context.InputParameters.Contains(ParameterName.Query) && context.OutputParameters.Contains(ParameterName.BusinessEntityCollection)))

return;

QueryExpression qe = context.InputParameters[ParameterName.Query] as QueryExpression;

if (qe == null) // Check it's a QueryExpression

return;

ConditionExpression cond = GetCondition(qe.Criteria, "returnedtypecode");

if (!(cond != null && cond.Operator == ConditionOperator.Equal && cond.Values.Length == 1 && cond.Values[0] is int)) // Check there is an equiality condition on returnedtypecode for an integer value

return;

int otc = (int)cond.Values[0];

if (otc1 != otc) // Check that we want to exclude views for this entity

return;

BusinessEntityCollection becViews = (BusinessEntityCollection)context.OutputParameters[ParameterName.BusinessEntityCollection];

if (!(becViews != null && becViews.EntityName == EntityName.savedquery.ToString())) // Check there are some views, and they are the right type

return;

//StringCollection scHide = _hideViews[otc];

for (int i = becViews.BusinessEntities.Count - 1; i >= 0; i--) // Iterate backwards, as items may be removed

{

DynamicEntity de = (DynamicEntity)becViews.BusinessEntities[i]; // BusinessEntityCollection is of type DynamicEntity

if (de.Properties.Contains("name") && (string)de.Properties["name"] == "Inactive Accounts") // Hide this view - i.e. remove it from the collection of returned views

becViews.BusinessEntities.RemoveAt(i);

}
