This method searches for the specified item and retrieves the zero-based index of its occurrence in this collection.

Syntax

virtual HRESULT STDMETHODCALLTYPE IndexOf(
    __in IXRRowDefinition* pRowDefinition,
    __out_opt int* pIndex
) = 0;

Parameters

pRowDefinition
[in] Pointer to an IXRRowDefinition object that represents the item to locate in this collection.

pIndex
[out] Pointer to an integer value that indicates the zero-based index of the location of the last occurrence of pRowDefinition within this collection.

Return Value

Returns an HRESULT that indicates success or failure.

Remarks

This method performs a linear search through the collection. Therefore, the average execution time is proportional to the number of items. You can retrieve the number of items by using IXRRowDefinitionCollection::GetCount.

By default, this method searches the collection starting at the last item and ending at the first item. Because an object cannot exist more than once in a visual tree, an item can occur only once in this object collection.
