        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
                {
                    if (e.Row.RowType == DataControlRowType.DataRow)

                        // To prevent the first click from posting back immediately

                        e.Row.Attributes["onclick"] = _jsSingle;

                        // Get the LinkButton control in the second cell

                        // Get the javascript which is assigned to this LinkButton
                        string _jsDouble = ClientScript.GetPostBackClientHyperlink(_doubleClickButton, "");
                        // Add this javascript to the ondblclick Attribute of the row

                protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
                {
                    GridView _gridView = (GridView)sender;

                    // Get the selected index and the command name
                    int _selectedIndex = int.Parse(e.CommandArgument.ToString());
                    string _commandName = e.CommandName;

                    switch (_commandName)
                    {
                        case ("SingleClick"):

    Design of grid

     <asp:GridView ID="GridView1" runat="server" BackColor="White" BorderColor="#DEDFDE" 
                BorderStyle="None" BorderWidth="1px" CellPadding="4" ForeColor="Black" GridLines="Vertical" 
                OnRowDataBound="GridView1_RowDataBound" OnRowCommand="GridView1_RowCommand">
                <FooterStyle BackColor="#CCCC99" />
                <Columns>                
                    <asp:ButtonField Text="SingleClick" CommandName="SingleClick" Visible="false"/>
                    <asp:ButtonField Text="DoubleClick" CommandName="DoubleClick" Visible="false"/>
                </Columns>
                <RowStyle BackColor="#F7F7DE" />
                <HeaderStyle BackColor="#6B696B" Font-Bold="True" ForeColor="White" />
                <SelectedRowStyle BackColor="#CE5D5A" Font-Bold="True" ForeColor="White" />
                <PagerStyle BackColor="#F7F7DE" ForeColor="Black" HorizontalAlign="Right" />            
                <AlternatingRowStyle BackColor="White" />
            </asp:GridView>
<asp:Label id="Message" runat="server" ForeColor="Red" Font-Bold="true"></asp:Label>

这是另一个只处理双击的解决方案：

在前端添加这些

OnRowDataBound="YourGrid_RowDataBound" OnRowEditing="YourGrid_RowEditing"

在后台

protected void YourGrid_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes["ondblclick"] = Page.ClientScript.GetPostBackClientHyperlink(YourGrid, "Edit$" + e.Row.RowIndex);           
            e.Row.Attributes["style"] = "cursor:pointer";
        }
    }
    
    protected void YourGrid_RowEditing(object sender, GridViewEditEventArgs e)
    {
        // Excecute your code here
        // Example:
        // get the grid
        GridView gv1 = (GridView)sender;
        //get the row
        GridViewRow gvr1 = (GridViewRow)gv1.Rows[e.NewEditIndex];
         // get data from a cell for the row
        string dataInCellOne= gvr1.Cells[1].Text.ToString();
        
       
    }
