GridViewModel.ProcessCustomBinding(GridViewCustomBindingGetDataRowCountHandler, GridViewCustomBindingGetDataHandler, GridViewCustomBindingGetSummaryValuesHandler, GridViewCustomBindingGetGroupingInfoHandler, GridViewCustomBindingGetUniqueHeaderFilterValuesHandler) Method

Delegates the implementation of grid view model population in the custom data binding mode to Model-layer functions specified via the method’s parameters.

Namespace: DevExpress.Web.Mvc

Assembly: DevExpress.Web.Mvc5.v18.2.dll

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 GridViewCustomBindingGetDataRowCountHandler delegate method allowing you to implement custom processing to return the total number of data rows. Implementation is required.
getDataMethod	GridViewCustomBindingGetDataHandler	A GridViewCustomBindingGetDataHandler delegate method allowing you to implement custom processing to return the data rows requested by the grid. Implementation is required.
getSummaryValuesMethod	GridViewCustomBindingGetSummaryValuesHandler	A GridViewCustomBindingGetSummaryValuesHandler delegate method allowing you to implement custom processing to calculate and return values of summaries required within the grid. Implementation is optional. It is required if you use summaries within the grid.
getGroupingInfoMethod	GridViewCustomBindingGetGroupingInfoHandler	A GridViewCustomBindingGetGroupingInfoHandler delegate method allowing 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). Implementation is optional, it is required if you use grouping within the grid.
getUniqueHeaderFilterValuesMethod	GridViewCustomBindingGetUniqueHeaderFilterValuesHandler	A GridViewCustomBindingGetUniqueHeaderFilterValuesHandler delegate method allowing you to implement custom processing to return unique values to be displayed in the header filter dropdown list invoked for a grid column. Implementation is optional, it is required if you display header filter buttons to use filtering within the grid.
