更新面板中的gridview pageindex

Question

我在更新面板中有一个gridview，第一次点击页面索引正在改变，但后来点击页面索引没有改变。但是点击时会触发事件。 这就是我绑定数据的方式。

protected void gvPurchaseDetails_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    gvPurchaseDetails.PageIndex = e.NewPageIndex;
    DetailsGridBind();
}

public void DetailsGridBind()
{

    DataSet dsInvoice = ObjDetail.GetPurchaseDetails();
    DataTable dtInvoice = dsInvoice.Tables[0];
    gvPurchaseDetails.DataSource = dtInvoice;
    gvPurchaseDetails.DataBind();     
}

Answer 1

为您的GridView设置EnableSortingAndPagingCallbacks="true"

默认设置为false

也在后面的代码中更新你的UpdatePanel

protected void gvPurchaseDetails_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    gvPurchaseDetails.PageIndex = e.NewPageIndex;
    DetailsGridBind();

    yourUpdatePanelId.Update();   // add this line of code was well
}
