我有一个具有 2 级 web 选项卡的页面。内容选项卡 FIXED 和 VARIABLE 依次具有 Web 选项卡。此 Web 选项卡加载有一个具有网格视图的用户控件。我的问题是 Gridview 中的文本框在从一个子选项卡转到下一个子选项卡时未清除。我尝试了所有可能的方法：1.将网格绑定到 null（数据源和 DatasoruceId）2.网格处置 3.网格列清除没有运气！！！..帮助！！！注意：我正在从 javascript 修改文本框中的数据。

加载 USer 控件的后端代码：
private void LoadInvestmentDetails(int investmentTypeId, WebTab currentWebTab, int tabIndex)
{
Panel panel = GetPanelToBeLoaded(investmentTypeId);
if (currentWebTab.Tabs[tabIndex].Controls.Count == 0)
{
currentWebTab.Tabs[tabIndex].Controls.Add(panel);
budgetDetailsControl.Initialize(investmentTypeId);
budgetDetailsControl.InvestmentDetailsSaved += new ProjectInvestmentDetailsSavedEventHandler(BudgetDetailsControl_BudgetDetailsSaved);
PreviouslyLoadedTab = int.Parse(currentWebTab.Tabs[currentWebTab.SelectedIndex].UserControlUrl);
}
// other code
}
private Panel GetPanelToBeLoaded(int investmentTypeId)
{
System.Web.UI.Control userControl = GetInvestmentDetailsUserControlUrl();
Panel panel = new Panel();
panel.Controls.Add(userControl);
budgetDetailsControl = (IProjectInvestmentDetailsControl)userControl;
budgetDetailsControl.InvestmentTypeID = investmentTypeId;
return panel;
}
private System.Web.UI.Control GetInvestmentDetailsUserControlUrl()
{
return LoadControl(ProjectCommonKeys.URL_PROJECT_BUDGET_DETAILS);
}
Usercontrol实现IprojectInvestmentDetails接口，首先调用UC的initialize函数进行绑定等
