单击gridview行时我需要显示一个模式弹出窗口（没有任何按钮），我设法通过单击gridview行来显示弹出窗口，但不知道将值绑定到模式弹出窗口中显示的文本框。所以我需要帮助

  1. 将 gridview 行（单击时）值绑定到模式弹出文本框
  2. 模态弹出文本框仅在单击编辑按钮（位于模态弹出窗口底部）时才可编辑
  3. 编辑工作完成后，点击保存按钮（位于编辑按钮旁边的底部）时应保存编辑后的数据

作为 asp.net 的新手，请尝试帮助我提出您对我的要求的建议。由于下面的代码能够显示弹出 wen 点击了 gridview 行，但建议我如何将值绑定到文本框：

protected void grid_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            GridViewRow row = e.Row;

            if (row.DataItem == null)
            {
                return;
            }

            try
            {
                switch (e.Row.RowType)
                {
                    case DataControlRowType.Header:
                        break;

                    case DataControlRowType.DataRow:
                        e.Row.Attributes.Add("onmouseover", "this.style.cursor='hand'");
                        e.Row.Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(grid, "Select$" + e.Row.RowIndex.ToString()));
                        e.Row.Attributes.Add("onclick", String.Format("javascript:$find('{0}').show();", ModalPopupExtender2.ClientID));


                        TextBox1.Text = grid.SelectedRow.Cells[0].Text;
                        TextBox2.Text = grid.SelectedRow.Cells[1].Text;
                        TextBox3.Text = grid.SelectedRow.Cells[2].Text;
                        TextBox4.Text = grid.SelectedRow.Cells[3].Text;
                        TextBox5.Text = grid.SelectedRow.Cells[4].Text;

                        ModalPopupExtender2.Show();
                        break;
                }
            }

            catch
            {
                return;
            }
        }

HTML 代码：

<asp:Panel ID="editpanel" runat="server">
            <table width="850px" border="1" class="color">
            <tr>
            <td align="center">
            <asp:Label ID="Label1" runat="server" Text="Firstname" Width="150px"></asp:Label>

            </td>
            </tr>
            <tr>
            <td>

            <asp:TextBox ID="TextBox4" runat="server" ></asp:TextBox>
            <asp:TextBox ID="TextBox5" runat="server"></asp:TextBox>
            </td>
            </tr>
            <tr>
                <td>
                        <asp:ImageButton ID="cancell" runat="server" onclick="cancell_Click"  
                        src="cancel.jpg" style="float:right; width: 16px;"

                     <asp:ImageButton ID="Edit" runat="server" onclick="edit_Click"  
                        src="edit.jpg" style="float:right; height: 16px; width: 16px;" 
                        ToolTip="To edit member" />
                </td>
                </tr>
            </table>   
            </asp:Panel>
    <asp:ModalPopupExtender ID="ModalPopupExtender2" runat="server" TargetControlID="modal2" PopupControlID="editpanel" BackgroundCssClass="modalBackground"></asp:ModalPopupExtender>


       <asp:ImageButton ID="modal2" runat="server" src="addmember.jpg" OnClick="modal2_click" Text="modal2" style="display:none;"/> // have created a dummy image button

使用它通过使用BindingSource（只是一个例子）将您的数据与文本框绑定：

textBoxid.DataBindings.Add(new Binding("Text", customersBindingSource, "ID"));
textBoxname.DataBindings.Add(new Binding("Text", customersBindingSource, "NAME"));
textBoxcity.DataBindings.Add(new Binding("Text", customersBindingSource, "City"));

要使您的文本框不可编辑，请使用以下命令：

private void EditButton_Click(object sender, EventArgs e)
        {
            if (textBoxid.ReadOnly == true)
            {
                textBoxid.ReadOnly = false;
                //how many text boxes you have, do the same here
            }
            else
            {
                textBoxid.ReadOnly = true;
                //how many text boxes you have, do the same here
            }
        }

UPDATE要保存您的编辑，只需使用所有新数据运行查询。
