Declaration

C#

public void ProcessCustomBinding(
    GridViewCustomBindingGetDataRowCountHandler getDataRowCountMethod,
    GridViewCustomBindingGetDataHandler getDataMethod,
    GridViewCustomBindingGetSummaryValuesHandler getSummaryValuesMethod,
    GridViewCustomBindingGetGroupingInfoHandler getGroupingInfoMethod,
    GridViewCustomBindingGetUniqueHeaderFilterValuesHandler getUniqueHeaderFilterValuesMethod
)

VB.NET

Public Sub ProcessCustomBinding(
    getDataRowCountMethod As GridViewCustomBindingGetDataRowCountHandler,
    getDataMethod As GridViewCustomBindingGetDataHandler,
    getSummaryValuesMethod As GridViewCustomBindingGetSummaryValuesHandler,
    getGroupingInfoMethod As GridViewCustomBindingGetGroupingInfoHandler,
    getUniqueHeaderFilterValuesMethod As GridViewCustomBindingGetUniqueHeaderFilterValuesHandler
)

Parameters

Name	Type	Description
getDataRowCountMethod	GridViewCustomBindingGetDataRowCountHandler	A delegate method that allows you to implement custom processing to return the total number of data rows.
getDataMethod	GridViewCustomBindingGetDataHandler	A delegate method that allows you to implement custom processing to return the data rows requested by the grid.
getSummaryValuesMethod	GridViewCustomBindingGetSummaryValuesHandler	A delegate method that allows you to implement custom processing to calculate and return values of summaries required within the grid.
getGroupingInfoMethod	GridViewCustomBindingGetGroupingInfoHandler	A delegate method that allows you to implement custom processing to return grouping information for group rows (the group value - key, and the number of data rows within the group - count).
getUniqueHeaderFilterValuesMethod	GridViewCustomBindingGetUniqueHeaderFilterValuesHandler	A delegate method that allows you to implement custom processing to return unique values to be displayed in the header filter dropdown list invoked for a grid column.
