如何在asp.net中删除gridview中的行

问题描述

protected void dropdownlist1_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (dropdownlist1.SelectedItem.ToString() == "Poor")
        {
            SetDropdowndetails("dropdownlist1", 1);
        }
        else
        {
             Selectednotpoor();
        }
    }

    private void SetDropdowndetails(string Dropdownname, Int32 Dropdownid)
    {
            SelectedDropdown = Dropdownname.ToString();
            hfnegativefeedback.Value = Dropdownid.ToString();
            Negativepnlpopup();
    }


    private void Negativepnlpopup()
    {
        try
        {

            textbox1.Text = "";
            DataTable dt = new DataTable();
            dt = (DataTable)ViewState["Remarks"];
            if (ViewState["Remarks"] != null)
            {
                for (int i = 0; i < dt.Rows.Count; i++)
                {
                    if (hfnegativefeedback.Value == dt.Rows[i][0].ToString())
                    {
                        textbox1.Text = dt.Rows[i][1].ToString();
                    }
                }
            }

            ModalPopupExtender1.TargetControlID = SelectedDropdown.ToString();
            textbox1.Focus();
            ModalPopupExtender1.Show();
            Pnlnegativefeedback.Visible = true;
        }
        catch (Exception e2)
        {

        }
    }

当我从下拉列表panelpopup中选择穷人时显示。

panelpopup如下。



NegativeFeedback



textbox1

ok（按钮）取消（按钮）



在textbox1中输入差的原因，然后单击确定按钮。然后选择下拉列表和textbox1原因，如gridview中所示。



如果假设用户想要点击优秀的drodpdownlist，那么糟糕的原因已经在gridview中删除了我该怎么办？使用csharp。





问候，

when i select the poor from the dropdownlist panelpopup is displaying.
the panelpopup as follows.

NegativeFeedback

textbox1
ok(Button) cancel(Button)

in the textbox1 type the reason for poor and click the ok button. then selected dropdown and textbox1 reason as has been shown in gridview.

if suppose user want to click the Excellent in drodpdownlist, the poor reason has been removed in the gridview for that how can i do using csharp.
