Question

我有一个Repeater，当数据量增加时，滚动条被显示。当我点击转发器内的任何一行时，它会被选中并在下一个div中相应地显示数据。假设我点击最后一条记录，数据会显示，行也会突出显示，但是滚动到达其初始位置而不是最后一个。

Answer 1

protected void Page_Load(object sender, EventArgs e) { ScrolBar();}

private void ScrolBar()
{
    HiddenField PosX = new HiddenField();
    HiddenField PosY = new HiddenField();

    HtmlControl Form1 = this.Master.FindControl("Form1") as HtmlControl;
    PosX.ID = "PosX";
    PosY.ID = "PosY";
    Form1.Controls.Add(PosX);
    Form1.Controls.Add(PosY);

    string script;
    script = "window.document.getElementById('" + PosX.ClientID + "').value = "
              + "window.document.getElementById('" + test1.ClientID + "').scrollLeft;"
              + "window.document.getElementById('" + PosY.ClientID + "').value = "
              + "window.document.getElementById('" + test1.ClientID + "').scrollTop;";

    this.ClientScript.RegisterOnSubmitStatement(this.GetType(), "SavePanelScroll", script);

    if (IsPostBack)
    {
        script = "window.document.getElementById('" + test1.ClientID + "').scrollLeft = "
                + "window.document.getElementById('" + PosX.ClientID + "').value;"
                + "window.document.getElementById('" + test1.ClientID + "').scrollTop = "
                + "window.document.getElementById('" + PosY.ClientID + "').value;";

        this.ClientScript.RegisterStartupScript(this.GetType(), "SetPanelScroll", script, true);
    }
}

只需在Page_Load中添加以下内容：

this.Page.MaintainScrollPositionOnPostBack = True

Answer 4

对于Repeater或GridView，请尝试以下操作：将控制放在div中并添加一个选项OnSorting

<div id="divGridView" runat="server" >
    <asp:GridView ID="Grid" runat="server"  OnSorting="Grid_OnSorting"
                OnDataBound="Grid_DataBound" >

代码文件上的

添加此方法：

protected void Grid_OnSorting(object sender, EventArgs e)
{
   divGridView.Page.SetFocus(Grid);        
}

如何在Gridview / Repeater中保留回发中的滚动位置
