public GridColumnCollection(GridTableView owner, ArrayList columns)Properties
Gets the number of columns added programmatically or declaratively.
[Browsable(false)]
public int Count { get; }Implements:
Note that this is not the actual number of column in a GridTableView. See also RenderColumns
Gets a value indicating whether the collection has a fixed size.
public bool IsFixedSize { get; }true if the collection has a fixed size; otherwise, false.
Implements:
Gets a value indicating whether the collection is read-only.
[Browsable(false)]
public bool IsReadOnly { get; }true if the collection is read-only; otherwise, false.
Implements:
Gets a value indicating whether access to the collection is synchronized (thread safe).
[Browsable(false)]
public bool IsSynchronized { get; }true if access to the collection is synchronized (thread safe); otherwise, false.
Implements:
Gets an object that can be used to synchronize access to the collection.
[Browsable(false)]
public object SyncRoot { get; }An object that can be used to synchronize access to the collection.
Implements:
public GridColumn this[int index] { get; }If the column/detail table structure is created after the control has been initialized (indicated by RadGrid.Init event ) the state of the columns/detail tables may have been lost. This happens when properties have been set to GridColumn/GridTableView instance before it has been added to the corresponding collection of Columns/DetailTables. Then a GridException is thrown with message: "Failed accessing GridColumn by index. Please verify that you have specified the structure of RadGrid correctly."
Methods
Adds a column object to the GridColumnCollection.
public void Add(GridColumn column)The GridColumn object to add to the collection.
Adds a column in the collection at the specified index.
public void AddAt(int index, GridColumn column)The index where the column will be inserted.
columnGridColumnThe column that will be inserted.
Removes all column from the collection.
public void Clear()Implements:
Determines whether the CridColumnCollection contains the value specified by the given GridColumn object.
public void CopyTo(Array array, int index)The one-dimensional Array that is the destination of the elements copied from ICollection. The Array must have zero-based indexing.
indexintThe zero-based index in array at which
copying begins.
array is null.
index is less than zero.
array is multidimensional.-or- The number of elements in the
source ICollection is greater than the available
space from index to the end of the destination array.-or-
The type of the source collection cannot
be cast automatically to the type of the destination array.
Implements:
