使用gridview和formview绑定维护FormView.PageIndex [英] Maintain FormView.PageIndex using gridview and formview bound

问题描述

我使用gridview / formview作为主/详细信息。 gridview和formview绑定到相同的数据源。有一个菜单控件可以控制要显示的formview控件。最初，我设置gridview = 0的selectedindex并显示相关的formview控件（数据源有3条记录，formview.PageCount = 3）。这没有问题。但是，当我选择另一条记录时，formview.PageCount = 3，一旦我点击另一个菜单项并返回之前点击了formview.PageCount = 1和formview.PageIndex = 0;



if（menuItm.Selected =Status Info）

{

int thisRow = theGrid.SelectedIndex;

if（theForm.PageIndex！= theGrid.SelectedIndex）

{

theForm.PageIndex = theGrid.SelectedIndex;

gvwtheGrid_SelectedIndexChanged（theGrid，null）

}



//有代码显示包含formview的视图

// theForm设置为可见。



如果设置了Form.PageIndex，我怎么能坚持？



谢谢，

I am using a gridview/formview to function as master/detail. The gridview and formview are bound to the same datasource. There is a menu control that controls which formview control to show. Initially, I am setting the selectedindex of the gridview = 0 and displaying the associated formview control (the datasource has 3 records, formview.PageCount = 3). This works without issues. However, when I select another record the formview.PageCount = 3, the formview is populated with the data, once I click another menu item and return to the one previously clicked the formview.PageCount = 1 and the formview.PageIndex = 0;

if (menuItm.Selected = "Status Info")
{
int thisRow = theGrid.SelectedIndex;
if (theForm.PageIndex != theGrid.SelectedIndex)
{
theForm.PageIndex = theGrid.SelectedIndex;
gvwtheGrid_SelectedIndexChanged(theGrid, null)
}

//there is code to show the view which contains the formview
//theForm is set to visible.

How can I persist the Form.PageIndex once it has been set?

Thanks,

推荐答案

因为页面正在重新加载，为了保持pageindex值，你使用了像隐藏字段/ querystrin这样的技术g保存该值并在加载时将所选索引设置为该值。

Because the page is getting reloaded, to persist pageindex value, you have use a technique like hidden field / querystring to save that value and on load set selected index to that value.
