Question

这里发生了一件奇怪的事。我已经按照我想要的方式运行了我的页面的功能，但是有一些布局问题并不是我真正想要的。因此，在尝试解决这些问题时，我发现构建新的母版页比使用默认的Site.master页面更容易。有些东西，我已经非常接近找到强迫我的一个文本框的方式比我想要的更窄。通过构建新的母版页，我解决了这个问题。但我同时在我的代码中引入了一个行为问题。

一旦我按照我想要的方式查看页面，我发现我在页面上遇到了asp：GridView的问题。我在GridView中创建了一个列，该列基于位于模板字段中的未绑定的Checkbox功能。

<asp:TemplateField HeaderText="Tag" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
    <asp:CheckBox runat="server" ID="TagRowChkBx" />
</ItemTemplate>
</asp:TemplateField>

在执行新的自定义母版页以修复布局问题之前，这些复选框将保留其检查，直到手动取消选中它们。在介绍新的母版页后，检查＆＃39;使用选择后离开。我读了这些复选框，以确定我想要批量影响更改的行。

我希望功能上恢复到剩余检查状态，直到用户选择取消选中它们。

以下是导致批量取消选中的代码（母版页更改的意外后果）：

protected void EditSelctedBtn_Click(object sender, EventArgs e)
{
    //Read the column select drop down List into Local Varriables 
    String SelectedColumnItem = ColumnSelectDDL.SelectedItem.ToString();
    String SelectedColumnValue = ColumnSelectDDL.SelectedValue.ToString();

    // Caputre the checked rows to List
    List<int> EditRows = new List<int>();
    List<string> recordnumber = new List<string>();
    foreach (GridViewRow grv in ActVulListGV.Rows)
    {
        if (((CheckBox)grv.FindControl("TagRowChkBx")).Checked == true)
        {
            //get current row rowindex if  checkbox  in it is checked 
            EditRows.Add(grv.RowIndex);
            //get the record number (RecID)
            recordnumber.Add(grv.Cells[2].Text.ToString());
        }
    }

// Place the List in an array 
int[] ERows = EditRows.ToArray();

// Check the DDL values to make sure that the user has made a selection Warn if not.    
     if (ColumnSelectDDL.SelectedValue == "Choose Column To Edit")
    {
        UserMessageLbl.ForeColor = System.Drawing.Color.Red;
        UserMessageLbl.Font.Bold = true;

        UserMessageLbl.Text = " *** You must choose a column to edit! ***";
    mpePopUp.Show();
    }
else
    {
// If Ticket # was selected enable Ticket # Panel
if (ColumnSelectDDL.SelectedValue.ToString() == "TicketNumber")
    {
        EditTicketNumPnl.Visible = true;
        EditTicketClosedPnl.Visible = false;
        EditNotesPnl.Visible = false;
        EditExceptionIDPnl.Visible = false;
        TicketNumFocusTbx.Text = "No Reference Data";
    }
    // If Ticket Closed was selected enable Ticket Closed Panel
    else if (ColumnSelectDDL.SelectedValue.ToString() == "TicketClosed")
    {
        EditTicketNumPnl.Visible = false;
        EditTicketClosedPnl.Visible = true;
        EditNotesPnl.Visible = false;
        EditExceptionIDPnl.Visible = false;
        TicketCldFocusTbx.Text = "";
    }
    // If Notes was selected enable Notes Panel
    else if (ColumnSelectDDL.SelectedValue.ToString() == "Notes")
    {
        EditTicketNumPnl.Visible = false;
        EditTicketClosedPnl.Visible = false;
        EditNotesPnl.Visible = true;
        EditExceptionIDPnl.Visible = false;
        NotesFocusTbx.Text = "No Reference Data";
    }
    // If Exception ID was selected enable Exception ID Panel
    else if(ColumnSelectDDL.SelectedValue.ToString() == "Exception_ID")
    {
        EditTicketNumPnl.Visible = false;
        EditTicketClosedPnl.Visible = false;
        EditNotesPnl.Visible = false;
        EditExceptionIDPnl.Visible = true;
        ExceptionIDFocusTbx.Text = "No Reference Data";
    }
    // format the popup and it's buttons
    EditColMsgLbl.Font.Bold = true;
    SelectedRowsMsgLbl.Font.Bold = true;

    ColEditPnlExt.Show();
    EditColLbl.Text = SelectedColumnItem;

    SelectedRowsLbl.Text = "";
    String divider = "";
    int ticks = 0;

    foreach (string record in recordnumber)
    {
        if (ticks > 0)
            {
                divider = ", ";
                ++ticks;
            }
        else
            {
                ++ticks;
            }
            SelectedRowsLbl.Text += divider.ToString() + record;
        }

    }
}
