GetModelUpdatesStatus Method

Gets the status of a single element in the central model.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 17.0.0.0 (17.0.484.0)
Since: 2012

Syntax

C# 
public static ModelUpdatesStatus GetModelUpdatesStatus(
	Document document,
	ElementId elementId
)
Visual Basic 
Public Shared Function GetModelUpdatesStatus ( _
	document As Document, _
	elementId As ElementId _
) As ModelUpdatesStatus
Visual C++ 
public:
static ModelUpdatesStatus GetModelUpdatesStatus(
	Document^ document, 
	ElementId^ elementId
)

Parameters

document
Type: Autodesk.Revit.DB Document
The document containing the element.
elementId
Type: Autodesk.Revit.DB ElementId
The id of the element.

Return Value

The status of the element in the local session versus the central model.

Remarks

This method returns a locally cached value which may not be up to date with the current state of the element in the central. Because of this, the return value is suitable for reporting to an interactive user (e.g. via a mechanism similar to Worksharing display mode), but cannot be considered a reliable indication of whether the element can be immediately edited by the application. Also, the return value may not be dependable in the middle of a local transaction. See the remarks on WorksharingUtils for more details.

For performance reasons, the model is not validated to be workshared, and the element id is also not validated; the element will not be expanded.

Examples

Copy C# 
public static bool AttemptToCheckoutInAdvance(Element element)
{
    Document doc = element.Document;
    String categoryName = element.Category.Name;

    // Checkout attempt
    ICollection<ElementId> checkedOutIds = WorksharingUtils.CheckoutElements(doc, new ElementId[] { element.Id });

    // Confirm checkout
    bool checkedOutSuccessfully = checkedOutIds.Contains(element.Id);

    if (!checkedOutSuccessfully)
    {
        TaskDialog.Show("Element is not checked out", "Cannot edit the " + categoryName + " element - " +
                        "it was not checked out successfully and may be checked out to another.");
        return false;
    }

    // If element is updated in central or deleted in central, it is not editable
    ModelUpdatesStatus updatesStatus = WorksharingUtils.GetModelUpdatesStatus(doc, element.Id);
    if (updatesStatus == ModelUpdatesStatus.DeletedInCentral || updatesStatus == ModelUpdatesStatus.UpdatedInCentral)
    {
        TaskDialog.Show("Element is not up to date", "Cannot edit the " + categoryName + " element - " +
                        "it is not up to date with central, but it is checked out.");
        return false;
    }

    return true;
}
Copy VB.NET 
Public Shared Function AttemptToCheckoutInAdvance(element As Element) As Boolean
    Dim doc As Document = element.Document
    Dim categoryName As [String] = element.Category.Name

    ' Checkout attempt
    Dim checkedOutIds As ICollection(Of ElementId) = WorksharingUtils.CheckoutElements(doc, New ElementId() {element.Id})

    ' Confirm checkout
    Dim checkedOutSuccessfully As Boolean = checkedOutIds.Contains(element.Id)

    If Not checkedOutSuccessfully Then
        TaskDialog.Show("Element is not checked out", "Cannot edit the " + categoryName + " element - " + "it was not checked out successfully and may be checked out to another.")
        Return False
    End If

    ' If element is updated in central or deleted in central, it is not editable
    Dim updatesStatus As ModelUpdatesStatus = WorksharingUtils.GetModelUpdatesStatus(doc, element.Id)
    If updatesStatus = ModelUpdatesStatus.DeletedInCentral OrElse updatesStatus = ModelUpdatesStatus.UpdatedInCentral Then
        TaskDialog.Show("Element is not up to date", "Cannot edit the " + categoryName + " element - " + "it is not up to date with central, but it is checked out.")
        Return False
    End If

    Return True
