Question

我正在使用 obout Grid 并正在创建 Details Grid 我想找出 Details Grid（child Grid）的当前页面索引我的网格在下面

<obout:DetailGrid runat="server" ID="GrdCategoryDetails" ForeignKeys="VENDOR_TYPE_LOOKUP_CODE,VENDOR_ID,ORG_ID"

                    </Template>
                </obout:GridTemplate>
            </Templates>
        </obout:DetailGrid>
    </DetailGrids>
</obout:DetailGrid>

这是我用于查找详细信息网格的当前页面索引的代码

Session["CurrentPageIndex"] = GrdvendorDetailsGrid.CurrentPageIndex.ToString();

Answer 1

要获取当前页面索引，您可以试试这个

        if(HttpContext.Current.Request["myGVPageId"] != null])
        {
            myGridview.PageIndex =  Convert.ToInt32(HttpContext.Current.Request["myGVPageId"]);
        }

Answer 2

您可以使用网格的 PageIndexChanging 事件来捕获页面索引并存储在会话中。

protected void GridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    int PageIndex = e.NewPageIndex;   
}

Answer 3

如果你在前端做分页，就这样做

<asp:TemplateField HeaderText="#">
    <ItemTemplate>
        <%# (Container.DataItemIndex + 1) + (gvReport.PageSize * gvReport.PageIndex) %>
    </ItemTemplate>
</asp:TemplateField>
