Data |
The DataColumn type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | AccumulateChangeData(Object, EventArgs) |
Accumulates the change data of the child. Currently only a flag is set to signal that the table has changed.
(Overrides SuspendableDocumentLeafNodeWithEventArgsAccumulateChangeData(Object, EventArgs)) |
| AccumulateChangeData(Int32, Int32, Boolean) | Accumulates the change data provided in the arguments into the m_ChangeData member. |
| AccumulatedChangeData_SetBackAfterResumeAndSuspend |
Sets the change data without further processing. This function is infrastructure and intended to use only in OnResume after the parent has suspended this node again.
(Inherited from SuspendableDocumentLeafNodeWithSingleAccumulatedDataT) |
| AccumulatedEventData_Clear |
Clears the accumulated event data.
(Inherited from SuspendableDocumentLeafNodeWithSingleAccumulatedDataT) |
| AccumulatedEventData_HasZeroOrOneEventArg |
Determines whether there is no or only one single event arg accumulated. If this is the case, the return value is true. If there is one event arg accumulated, it is returned in the argument singleEventArg.
The return value is false if there is more than one event arg accumulated. In this case the singleEventArg is null on return, and the calling function should use AccumulatedEventData to
enumerate all accumulated event args.
(Inherited from SuspendableDocumentLeafNodeWithSingleAccumulatedDataT) |
 | Add | |
| Append | Appends data from another column to this column |
| AppendToPosition | Appends data from another column to this column |
| ChildDisposeMemberT |
Helper function to dispose a child node of this instance. It helps to ensure the correct order: first, the child node is set to null and only then the child node is disposed.
(Inherited from SuspendableDocumentNodeBase) |
| Clear | Clears all rows. |
| Clone | Creates a cloned instance of this object. |
| Contains | |
| CopyDataFrom | Copies the contents of another column o to this column. An exception should be thrown if the data types of both columns are incompatible. |
| CopyHeaderInformationFrom | copies the header information, like label and so on from another column to this column ColumnName and ColumnNumber is not copied! |
| CopyTo | |
| CreateColumnOfSelectedRows(IAscendingIntegerCollection) | Creates a new column, consisting only of the selected rows of the original column. |
 | CreateColumnOfSelectedRows(DataColumn, IAscendingIntegerCollection) | Creates a new column, consisting only of the selected rows of the original column x. If x is null, a new DoubleColumn will be returned, consisting of the selected row indices. |
| CreateColumnOfSelectedRows(DataColumn, IAscendingIntegerCollection, Int32) | Creates a new column, consisting only of the selected rows of the original column x. If x is null, a new DoubleColumn will be returned, consisting of the selected row indices. |
| CreateInstanceOfType | |
| CutToMaximumLength | Cuts the column to the provided length. The actual length of the column may be less than the provided parameter if the column contains empty elements. |

(Inherited from SuspendableDocumentNodeBase) |
| Dispose(Boolean) |
Releases unmanaged and - optionally - managed resources.

Called if some member of this instance itself has changed.
(Inherited from SuspendableDocumentLeafNode) |
| EhSelfChanged(Int32, Int32, Boolean) | This function has to be called by derived classes if any changes in their data occur. |
| EhSelfTunnelingEventHappened(TunnelingEventArgs) |
Is called by this instance if a tunneling event happened into this instance. The tunneling event triggers the TunneledEvent and is additionally distributed to all childs of this instance.
(Inherited from SuspendableDocumentNodeBase) |
| EhSelfTunnelingEventHappened(TunnelingEventArgs, Boolean) |
Is called by this instance if a tunneling event happened into this instance.
The tunneling event triggers the TunneledEvent and is - depending on the provided parameter - also distributed to all childs of this instance.
(Inherited from SuspendableDocumentNodeBase) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| Finalize |
Finalizes an instance of the SuspendableDocumentNodeBase class.
(Inherited from SuspendableDocumentNodeBase) |
| GetColumnStyleType | Returns the type of the associated ColumnStyle for use in a worksheet view. |
| GetColumnTypeAppropriateForElementType | Gets the column typeappropriate for the given element type. Example: when typeof(double) is given, the return value is typeof(DoubleColumn). |

| GetType | Gets the Type of the current instance. (Inherited from Object) |
| GetVariantAt | This returns the value at a given index i as AltaxoVariant. |
| HandleLowPriorityChildChangeCases |
Handles the cases when a child changes, but a reaction is neccessary only if the table is not suspended currently.
(Inherited from SuspendableDocumentLeafNode) |
| IndexOf | |
| IndicesOf | Gets all indices where the element is equal to the value given in item. |
| Insert | |
| InsertRows | Inserts nCount empty rows before row number nBeforeRow. |
| IsElementEmpty | This function is used to determine if the element at index i is valid or not. If it is valid, the derived class function has to return false. If it is empty or not valid, the function has to return true. |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| OnAboutToBeResumed |
Is called when the suspend level is still 1 (one), but is about to fall to zero, i.e. shortly before the call to OnResume. This function is not called before OnResumeSilently!
(Inherited from SuspendableDocumentLeafNode) |
| OnChanged |
Fires the change event with the EventArgs provided in the argument.
(Inherited from SuspendableDocumentNodeBase) |
| OnResume |
Is called when the suspend level falls down from 1 to zero by a call to Resume or a call to [M:Altaxo.Main.ISuspendToken.Dispose()].
(Inherited from SuspendableDocumentLeafNode) |
| OnResumeSilently |
Is called when the suspend level falls down from 1 to zero by a call to ResumeSilently.
The implementation should delete any accumulated events, should also disarm the suspendTokens of the childs of this object, and should not fire any Changed events nor set the change state of the object to dirty.
(Inherited from SuspendableDocumentLeafNode) |
| OnSuspended |
Called when the suspend level has just gone from 0 to 1, i.e. the object was suspended.
(Inherited from SuspendableDocumentLeafNode) |
| OnTunnelingEvent |
Fires the TunneledEvent event.
(Inherited from SuspendableDocumentNodeBase) |
| Remove | |
| RemoveAt | |
| RemoveRows | Removes a number of rows (given by nCount) beginning from nFirstRow, i.e. remove rows number nFirstRow ... nFirstRow+nCount-1. |
| Resume(ISuspendToken) |
Resumes changed events by calling Resume for the provided suspend token, and setting the reference to the suspend token to null.
If Event data were accumulated during the suspended state, a changed event is triggered for each event data.
(Inherited from SuspendableDocumentNodeBase) |
| Resume(ISuspendToken, EventFiring) |
Resumes changed events, either with taking the accumulated event data into account (see Resume(ISuspendToken)) or discarding the accumulated event data (see ResumeSilently(ISuspendToken),
depending on the provided argument eventFiring.
(Inherited from SuspendableDocumentNodeBase) |
| ResumeCompleteTemporarily |
Resumes the object completely for only a short time. Thus, if object was suspended before, it will be suspended again when the function returns.
(Inherited from SuspendableDocumentLeafNode) |
| ResumeCompleteTemporarilyGetToken |
Resumes the object completely for the time the returned token is referenced and not disposed.
The return value is a token that had 'absorbed' the suspend count of the object, resulting in the suspend count
of the object dropped to 0 (zero). When the returned token is finally disposed, the suspend count of the object is increased again by the 'absorbed' suspend count.
(Inherited from SuspendableDocumentLeafNode) |
| ResumeSilently |
Resumes changed events by calling Resume for the provided suspend token, and setting the reference to the suspend token to null.
All event data accumulated during the suspended state are discarded, and thus no change event is triggered even if the instance has changed during the suspended state.
(Inherited from SuspendableDocumentNodeBase) |
