C# 如何防止在编辑模式下选择gridview行。（asp.net服务器端）

我有一个充满数据的表，如果用户单击一行，所选行中的数据将填充输入字段。我创建了一个onclick函数，允许用户选择正在工作的gridview中的行，我想要的是，当用户单击编辑按钮时，用户不能选择所选行以外的其他行（禁用行选择），当用户单击保存/取消时，行选择再次启用。我不太会使用asp.net，有人能帮我吗

这是gridview代码

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
    DataKeyNames="CASE_KEY" DataSourceID="SqlDataSource1" Height="250px" 
    Width="1109px" BackColor="White" BorderColor="#999999" BorderStyle="None" 
    BorderWidth="1px" CellPadding="3" GridLines="Vertical" onrowcommand="GridView1_RowCommand"
    OnRowDataBound="GridView1_RowDataBound">
    <AlternatingRowStyle BackColor="Gainsboro" />
    <Columns>
        <asp:buttonfield buttontype="Link" commandname="Select" text="Select" Visible="False" />
        <asp:BoundField DataField="CASE_KEY" HeaderText="CASE_KEY" ReadOnly="True" 
            SortExpression="CASE_KEY" Visible="False" />
        <asp:BoundField DataField="DEPARTMENT_CASE_NUMBER" 
            HeaderText="Department Case #" SortExpression="DEPARTMENT_CASE_NUMBER" />
        <asp:BoundField DataField="DEPARTMENT_NAME" HeaderText="Department" 
            SortExpression="DEPARTMENT_NAME" />
        <asp:BoundField DataField="CHARGE" HeaderText="Charge" 
            SortExpression="CHARGE" />
        <asp:BoundField DataField="LAB_CASE" HeaderText="Lab Case #" 
            SortExpression="LAB_CASE" />
        <asp:BoundField DataField="OFFENSE_DATE" HeaderText="Incident Report Date" 
            SortExpression="OFFENSE_DATE" />
    </Columns>

您无需创建自己的按钮来选择、编辑/取消更新操作。Asp.net GridView具有处理这些操作的内置选项

我已经修改了GridView代码，使其具有内置的编辑按钮，请参考下面的内容

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
DataKeyNames="CASE_KEY" DataSourceID="SqlDataSource1" Height="250px" 
Width="1109px" BackColor="White" BorderColor="#999999" BorderStyle="None" 
BorderWidth="1px" CellPadding="3" GridLines="Vertical"  
 >
<AlternatingRowStyle BackColor="Gainsboro" />
<Columns>
    <asp:CommandField ShowEditButton="true" /> 
    <asp:BoundField DataField="CASE_KEY" HeaderText="CASE_KEY" ReadOnly="True" 
        SortExpression="CASE_KEY" Visible="False" />
    <asp:BoundField DataField="DEPARTMENT_CASE_NUMBER" 
        HeaderText="Department Case #" SortExpression="DEPARTMENT_CASE_NUMBER" />
    <asp:BoundField DataField="DEPARTMENT_NAME" HeaderText="Department" 
        SortExpression="DEPARTMENT_NAME" />
    <asp:BoundField DataField="CHARGE" HeaderText="Charge" 
        SortExpression="CHARGE" />
    <asp:BoundField DataField="LAB_CASE" HeaderText="Lab Case #" 
        SortExpression="LAB_CASE" />
    <asp:BoundField DataField="OFFENSE_DATE" HeaderText="Incident Report Date" 
        SortExpression="OFFENSE_DATE" />
</Columns>

您可以通过GridView1_行编辑、GridView1_行取消编辑和GridView1_行更新后的代码上的相应事件来处理编辑、更新和取消编辑操作。希望这能有所帮助。谢谢。

您好，谢谢您的回答，我知道有这样一个函数，但我正在以不同的方式使用它。

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" 
             Text="Edit" />
    &nbsp;
<asp:Button ID="Button2" runat="server" onclick="Button2_Click" 
            Text="Save" Enabled="false"/>
     &nbsp;
<asp:Button ID="Button3" runat="server" onclick="Button3_Click" 
 Text="Cancel" Enabled="false"/>

protected void GridView1_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
    {
       if (e.Row.RowType == DataControlRowType.DataRow)
        {
            //Change the mouse cursor to Hand symbol to show the user the cell is selectable
            e.Row.Attributes["onmouseover"] = "this.style.cursor='hand';this.style.textDecoration='underline';this.style.cursor='Pointer'";
            e.Row.Attributes["onmouseout"] = "this.style.textDecoration='none';";

            //Attach the click event to each cells
            e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(this.GridView1, "Select$" + e.Row.RowIndex);
        }
    }

    protected void GridView1_RowCommand(Object sender, GridViewCommandEventArgs e)
    {
        // If multiple buttons are used in a GridView control, use the
        // CommandName property to determine which button was clicked.
        if (e.CommandName == "Select")
        {
            // Convert the row index stored in the CommandArgument
            // property to an Integer.
            int index = Convert.ToInt32(e.CommandArgument);

            // Retrieve the row that contains the button clicked 
            // by the user from the Rows collection.
            GridViewRow row = GridView1.Rows[index];

            // Populate the input box with the value of selected row.     
            GridViewRow gr = GridView1.Rows[index];
            TextBox1.Text = gr.Cells[2].Text;
            TextBox2.Text = gr.Cells[3].Text;
            TextBox3.Text = gr.Cells[4].Text;
            TextBox4.Text = gr.Cells[5].Text;
            TextBox5.Text = gr.Cells[6].Text;

        }
    }    


    protected void Button1_Click(object sender, EventArgs e)
    {
        Button1.Enabled = false;
        Button2.Enabled = true;
        Button3.Enabled = true;
        TextBox1.Enabled = true;
        TextBox2.Enabled = true;
        TextBox3.Enabled = true;
        TextBox4.Enabled = true;
        TextBox5.Enabled = true;
    }

    protected void Button2_Click(object sender, EventArgs e)
    {
        Button1.Enabled = true;
        Button2.Enabled = false;
        Button3.Enabled = false;
        TextBox1.Enabled = false;
        TextBox2.Enabled = false;
        TextBox3.Enabled = false;
        TextBox4.Enabled = false;
        TextBox5.Enabled = false;
    }

    protected void Button3_Click(object sender, EventArgs e)
    {
        Button1.Enabled = true;
        Button2.Enabled = false;
        Button3.Enabled = false;
        TextBox1.Enabled = false;
        TextBox2.Enabled = false;
        TextBox3.Enabled = false;
        TextBox4.Enabled = false;
        TextBox5.Enabled = false;
       }
