AddOnSchemaChangedListener Represents a data source for use in components which need advanced access to data.

public interface DataSource

bool DeferAutoRefresh { get; set; }

IgbFilterExpressionCollection FilterExpressions { get; }

int FirstVisibleIndexRequested { get; set; }

bool IncludeSummaryRowsInSection { get; set; }

bool IsSectionCollapsable { get; set; }

bool IsSectionContentVisible { get; set; }

bool IsSectionExpandedDefault { get; set; }

bool IsSectionHeaderNormalRow { get; set; }

bool IsSectionSummaryRowsAtBottom { get; set; }

int LastVisibleIndexRequested { get; set; }

string[] PrimaryKey { get; set; }

bool ShouldEmitSectionHeaders { get; set; }

bool ShouldEmitShiftedRows { get; set; }

bool ShouldEmitSummaryRows { get; set; }

DataSourceSummaryScope SummaryScope { get; set; }

DataSourceUpdateNotifier UpdateNotifier { get; set; }

Called to clear all pinned rows.

Task ClearPinnedRowsAsync()

Clones this data source instance, copying the summary, grouping, filter and sorting settings into the new instance.

Task<DataSource> CloneAsync()

Called to make sure a queued refresh of the data source has been applied before continuing. Should only be needed if you are trying to synchronously examine the results of changing settings on the data source. Note, for a virtual data source, the data source itself may be waiting for other synchronous requests to actualize data. This call will not wait for those, but will only make sure the appropriate requests are in flight from the settings changes

Task FlushAutoRefreshAsync()

bool GetIsRowExpandedAtIndex(int rowIndex)

Gets the expansion state for a row.

Task<bool> GetIsRowExpandedAtIndexAsync(int rowIndex)

The row to check.

object GetItemProperty(object item, string propertyName)

Task<object> GetItemPropertyAsync(object item, string propertyName)

object GetItemPropertyAtIndex(int index, string valueName)

Task<object> GetItemPropertyAtIndexAsync(int index, string valueName)

string GetMainValuePath(DataSourceRowType rowType)

Gets the type of row at the specified index.

Task<string> GetMainValuePathAsync(DataSourceRowType rowType)

IgbDataGridSummaryResult[] GetRootSummaryResults()

Gets the summary results for the root level.

Task<IgbDataGridSummaryResult[]> GetRootSummaryResultsAsync()

int GetRootSummaryRowCount()

Gets the number of summary rows at the root level.

Task<int> GetRootSummaryRowCountAsync()

int GetRowLevel(int rowIndex)

Gets the hierarchy level of the row.

Task<int> GetRowLevelAsync(int rowIndex)

The row to check.

DataSourceRowType GetRowType(int rowIndex)

Gets the type of row at the specified index.

Task<DataSourceRowType> GetRowTypeAsync(int rowIndex)

IgbDataGridSummaryResult[][] GetSectionSummaryResults(int sectionIndex)

Gets the summary results for a specific section.

Task<IgbDataGridSummaryResult[][]> GetSectionSummaryResultsAsync(int sectionIndex)

int GetStickyRowPriority(int row)

Gets the priority of a pinned row, which defines how it interacts with other pinned rows.

Task<int> GetStickyRowPriorityAsync(int row)

The index of the row to get the priority for.

int IndexOfItem(object item)

Called to return the index for an item contained in the data source, or -1, if the item can't be found, or this action isn't currently supported.

Task<int> IndexOfItemAsync(object item)

The item for which to find the index.

int IndexOfKey(object[] key)

Task<int> IndexOfKeyAsync(object[] key)

bool IsExclusivelySticky(int row)

Gets whether the row is allowed to push other sticky rows with the same priority.

Task<bool> IsExclusivelyStickyAsync(int row)

The index of the row to get the exclusivity for.

bool IsPlaceholderItem(int index)

Returns true if the item at the requested index is a placeholder item and has not been actualized.

Task<bool> IsPlaceholderItemAsync(int index)

bool IsRowPinned(int row)

Returns whether the row is pinned.

Task<bool> IsRowPinnedAsync(int row)

The index of the row.

bool IsRowSpanning(DataSourceRowType rowType)

Returns whether the requested row type is considered a spanning element for the data source. Spanning elements have a single complex value rather than the current schema of the data source.

Task<bool> IsRowSpanningAsync(DataSourceRowType rowType)

void PinRow(object[] key)

Task PinRowAsync(object[] key)

Called to manually queue a refresh of the data source.

Task QueueAutoRefreshAsync()

Called to synchronously refresh the data source.

DataSourceSchemaPropertyType ResolveSchemaPropertyType(string propertyPath)

Resolve a property or property path to its value type.

Task<DataSourceSchemaPropertyType> ResolveSchemaPropertyTypeAsync(string propertyPath)

The property or property path.

void SetIsRowExpandedAtIndex(int rowIndex, bool isExpanded)

Task SetIsRowExpandedAtIndexAsync(int rowIndex, bool isExpanded)

void UnpinRow(object[] key)

Task UnpinRowAsync(object[] key)
