Question

请看一下：

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    int index = Convert.ToInt32(e.CommandArgument);

    if (e.CommandName == "Edit")
    {
        GridView1.EditIndex = index;
    }
}

此代码段将整个gridview-row置于编辑模式。

但是我需要将一行的第3和第5个单元格（假设）放入编辑模式。

我该怎么办？

有些人可能会建议不使用编辑模板。但我只使用后面的代码来操作gridview中的数据，如下所示：

ASPX：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="GridView___Test._Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
</head>

<body>
    <form id="form1" runat="server">
    <div>

        <asp:GridView ID="GridView1" runat="server" Font-Names="Verdana" Font-Size="Small" AutoGenerateColumns="False" OnRowCancelingEdit="GridView1_RowCancelingEdit" OnRowCommand="GridView1_RowCommand" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating">            
        </asp:GridView>

    </div>
    </form>
</body>

</html>

public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                CreateGridView();
            }
        }

        private void CreateGridView()
        {
            GridView1.Columns.Clear();

            DataTable dataTable = Book.GetBooksDataSet().Tables[0];

            CommandField cf = new CommandField();
            cf.ShowEditButton = true;

            GridView1.Columns.Add(cf);

            foreach (DataColumn c in dataTable.Columns)
            {
                BoundField boundField = new BoundField();

                boundField.DataField = c.ColumnName;
                boundField.HeaderText = c.ColumnName;

                GridView1.Columns.Add(boundField);
            }

            GridView1.DataSource = dataTable;
            GridView1.DataBind();
        }

        protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            int index = Convert.ToInt32(e.CommandArgument);

            if (e.CommandName == "Edit")
            {
                GridView1.EditIndex = index;

                GridViewRow selectedRow = ((GridView)e.CommandSource).Rows[index];

                string id = selectedRow.Cells[1].Text;
                string isbn = selectedRow.Cells[2].Text;

                CreateGridView();
            }
            else if (e.CommandName == "Update")
            {
                LinkButton updateButton = (LinkButton)e.CommandSource;

                DataControlFieldCell dcfc = (DataControlFieldCell)updateButton.Parent;

                GridViewRow gvr = (GridViewRow)dcfc.Parent;

                ControlCollection cc = gvr.Cells[1].Controls;

                TextBox tb = (TextBox)cc[0];

                GridView1.EditIndex = -1;

                CreateGridView();
            }
        }

        protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
        {
        }

        protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
        {
        }

        protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
        {            
        }
    }

我的观点是尽可能避免使用asp.net脚本。

还有可能只使用代码才能使用脚本。

看看以下是否有帮助。即将不可编辑的列设置为InsertVisible为false。此外，您可以将以下代码放在GridView1_DataBinding事件中。删除行GridView1.DataBind（）;然后再次调用GridView1.DataBind（）;你在哪里调用这种方法。

private void CreateGridView()
        {
            GridView GridView1 = new GridView();
            GridView1.Columns.Clear();

            DataTable dataTable = Book.GetBooksDataSet().Tables[0];

            CommandField cf = new CommandField();
            cf.ShowEditButton = true;

            GridView1.Columns.Add(cf);

            int colCount = 1;
            foreach (DataColumn c in dataTable.Columns)
            {
                BoundField boundField = new BoundField();

                boundField.DataField = c.ColumnName;
                boundField.HeaderText = c.ColumnName;
                if (colCount == 3 | colCount == 5)
                {
                    boundField.InsertVisible = true;
                }
                else
                {
                    boundField.InsertVisible = false;
                }

                colCount++;
                GridView1.Columns.Add(boundField);
            }

            GridView1.DataSource = dataTable;
            GridView1.DataBind();
        }
