Question

我已经在ASP.NET应用程序中编写了代码，如

  protected void chkbox_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox chkbox = sender as CheckBox;
        GridViewRow currentRow = chkbox.NamingContainer as GridViewRow;
        Label lblJurisdiction = grdView.Rows[currentRow.RowIndex].FindControl("lblJurisdiction") as Label;
        RequiredFieldValidator rfv = grdView.Rows[currentRow.RowIndex].FindControl("ValReqED") as RequiredFieldValidator;
        RequiredFieldValidator rfvExpD = grdView.Rows[currentRow.RowIndex].FindControl("ValReqExpD") as RequiredFieldValidator;
        RequiredFieldValidator rfvLN = grdView.Rows[currentRow.RowIndex].FindControl("ValReqLN") as RequiredFieldValidator;
        if (!chkbox.Checked)
        {
            rfv.Enabled = false;
            rfvExpD.Enabled = false;
            rfvLN.Enabled = false;
            string JurisdictionRemoved = lblJurisdiction.Text + ",";
            string Jurisdiction = txtJurisdiction.Text;
            string ReplacedJurisdiction = Jurisdiction.Replace(JurisdictionRemoved, "");
            txtJurisdiction.Text = ReplacedJurisdiction;
        }
        else
        {
            string Jurisdiction = txtJurisdiction.Text;
            txtJurisdiction.Text = Jurisdiction + "," + lblJurisdiction.Text.ToString(); 
        }
    }

请注意，字符串Jurisdictions包含一组诸如

之类的司法管辖区

     Delaware,Georgia,Illinois,Kansas,Maine

字符串JurisdictionRemoved只包含一个管辖区（用户将取消选中该复选框）

   Georgia

然后txtJurisdicton必须包含

     Delaware,Illinois,Kansas,Maine

如果字符串JurisdictionRemoved包含“Maine”，则上面的代码不起作用，则不会删除。

现在我希望每当用户取消选中要从txtJurisdiction文本框中删除管辖权的复选框时，每当用户检查复选框时，相应的权限应该附加到txt辖区。让我们假设用户再次检查了“Georgia” 那么文本框应该包含

       Delaware,Georgia,Illinois,Kansas,Maine

上面的代码不能像这样工作。此外，我希望它按字母顺序在文本框中附加检查的管辖权，并应消除冗余状态。请帮帮我!!!

Answer 1

要解决此问题，您可以这样做

使用append函数
使用条件
用户split方法创建新字符串。
将该值分配给您的文本框。

实施例

String.Join

从gridview中添加文本并对其进行排序
