Question

我对开发表达非常新。

<dx:ASPxGridView ID="aspxgvOMContracts" runat="server" KeyFieldName="OMContractId" Settings-UseFixedTableLayout="true"

                                <SettingsEditing Mode="Inline" />

                                    <dx:GridViewCommandColumn ButtonType="Image" Width="65px" VisibleIndex="0">
                                        <EditButton Visible="True" Image-Url="../Content/Images/icon_edit.png">

                                        </DeleteButton>
                                        <ClearFilterButton Visible="True">
                                        </ClearFilterButton>

                                            </dx:ASPxLabel>
                                        </HeaderTemplate>--%>
                                    </dx:GridViewCommandColumn>
                                    <dx:GridViewDataComboBoxColumn FieldName="OrganisationName" Caption="OrganisationName" VisibleIndex="1">
                                        <PropertiesComboBox TextField="CompanyName" ValueField="OrganisationId" ValueType="System.Int32">
                                        </PropertiesComboBox>
                                    </dx:GridViewDataComboBoxColumn>
                                    <dx:GridViewDataTimeEditColumn FieldName="DateAnnounced" Caption="DateAnnounced" VisibleIndex="2">
                                    </dx:GridViewDataTimeEditColumn>
                                    <dx:GridViewDataTextColumn FieldName="Cost" Caption="Cost" VisibleIndex="3">
                                    </dx:GridViewDataTextColumn>
                                    <dx:GridViewDataTextColumn FieldName="CostCurrency" Caption="Cost Currency" VisibleIndex="4">
                                    </dx:GridViewDataTextColumn>
                                </Columns>

                            </dx:ASPxGridView>

在代码后面我将数据绑定为

aspxgvOMContracts.DataSource = phase.OMContracts;
        aspxgvOMContracts.DataBind();

此处phase.OMContracts的类型为List（）

现在，当我编辑任何行时，我需要修改后的集合。如何获得修改后的集合？

Answer 1

您已经分配了AspxGridview控件的DataSource属性，然后您可以直接从DataSource属性访问分配的已分配List，它是一个读写属性。

查看文档：

ASPxDataWebControlBase.DataSource Property

获取或设置数据绑定控件从中检索的对象它的数据项列表。

来自：Get GridView data source to Data table

如果你在每次回发时绑定gridview，那么你可以获得DataTable dt = GridView1.DataSource作为DataTable;

与List<SomeType> data = grid.DataSource as List<SomeType>;

相同

希望这有帮助..
