        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
                {
                    if (e.Row.RowType == DataControlRowType.DataRow)
                    {
                        // Get the LinkButton control in the first cell
                        LinkButton _singleClickButton = (LinkButton)e.Row.Cells[0].Controls[0];
                        // Get the javascript which is assigned to this LinkButton

          string _jsSingle = ClientScript.GetPostBackClientHyperlink(_singleClickButton, "");
                        // To prevent the first click from posting back immediately 
                        // (therefore giving the user a chance to double click) pause the 
                        // postback for 300 milliseconds by using setTimeout
                        _jsSingle = _jsSingle.Insert(11, "setTimeout(\"");
                        _jsSingle += "\", 300)";
                        // Add this javascript to the onclick Attribute of the row
                        e.Row.Attributes["onclick"] = _jsSingle;

                        // Get the LinkButton control in the second cell
                        LinkButton _doubleClickButton = (LinkButton)e.Row.Cells[1].Controls[0];
                        // Get the javascript which is assigned to this LinkButton
                        string _jsDouble = ClientScript.GetPostBackClientHyperlink(_doubleClickButton, "");
                        // Add this javascript to the ondblclick Attribute of the row

                    }

                    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"):
                            _gridView.SelectedIndex = _selectedIndex;
                            this.Message.Text += "Single clicked GridView row at index " + _selectedIndex.ToString() + "<br />";
                            break;
                        case ("DoubleClick"):
                            Response.Write("<script type='text/javascript'>detailedresults=window.open('Patient//PatientDicomViewPage.aspx');</script>");

                            // Response.Redirect("ViewPatient.aspx");
                            this.Message.Text += "Double clicked GridView row at index " + _selectedIndex.ToString() + "<br />";
                            break;
                    }
                }

這是另一種僅處理雙擊的解決方案：

在前端添加這些

OnRowDataBound="YourGrid_RowDataBound" OnRowEditing="YourGrid_RowEditing" 

在后端

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();
        
       
    }
