C# 如何申请；只读“；在编辑模式下使用BoundField在gridview文本框中

我想在使用Boundsfield的文本框上设置只读。到目前为止，enabled正在工作，但它在RowUpdate中没有价值

 protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        var nopoject = ddlproject.SelectedValue.ToString();
        Int32 curntMonth = Convert.ToInt32(DateTime.Now.ToString("MM"));
        int Mont1 = curntMonth - 1;
        var Comtext = "Rst" + Mont1.ToString();
        GridView1.EditIndex = e.NewEditIndex;
        BindData();

        foreach (GridViewRow row in GridView1.Rows)
        {              
            for (int i = 0; i < GridView1.Columns.Count; i++)
            {
                String headertext = GridView1.Columns[i].HeaderText;
                String cellText = row.Cells[i].Text;

                if (Comtext == "Rst1")
                {
                     GridView1.Rows[e.NewEditIndex].Cells[i].Enabled = true;                         
                }}}

请告知。内联编辑时，我希望以编程方式在boundsfield上设置只读 多谢各位

您还可以在行编辑事件中将文本框设置为只读，如下所示

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        var nopoject = ddlproject.SelectedValue.ToString();
        Int32 curntMonth = Convert.ToInt32(DateTime.Now.ToString("MM"));
        int Mont1 = curntMonth - 1;
        var Comtext = "Rst" + Mont1.ToString();
        GridView1.EditIndex = e.NewEditIndex;
        BindData();

        foreach (GridViewRow row in GridView1.Rows)
        {              
            for (int i = 0; i < GridView1.Columns.Count; i++)
            {
                String headertext = GridView1.Columns[i].HeaderText;
                String cellText = row.Cells[i].Text;

                if (Comtext == "Rst1")
                {
                     //GridView1.Rows[e.NewEditIndex].Cells[i].Enabled = true;                         
                     TextBox tx_chdets = (TextBox)GridView1.Rows[e.NewEditIndex].FindControl(“TextBox1”);
                     if(tx_chdets!=null)
                    {
                        tx_chdets.Readonly=true;
                    }
                }
            }
        }
    }

protectedvoid GridView1\u行编辑（对象发送方，GridViewEditEventArgs e）

var noproject=ddlproject.SelectedValue.ToString（）；

您可以使用此代码段

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        if ((e.Row.RowState & DataControlRowState.Edit) > 0)
        {
            TextBox textBox = e.Row.Cells[0].Controls[0] as TextBox;
            textBox.Enabled = false;
        }
    }
}

我只想在编辑的时候收到回信。很抱歉回信迟了。FindControl（“TextBox1”）=如何通过循环查找？@user3538475-我已经编辑了上述代码。请。复习一下。谢谢你……但是。。。tx_chdets返回空值。TextBox tx_chdets=（TextBox）GridView1.Rows[e.NewEditIndex].FindControl（“TextBox1”）；在此代码中，用您的文本框Idi替换文本框1。仅当行编辑时，我希望看到。很抱歉回复太晚。FindControl（“TextBox1”）=如何通过循环查找？@user3538475-我已经编辑了上述代码。请。复习一下。谢谢你……但是。。。tx_chdets返回空值。TextBox tx_chdets=（TextBox）GridView1.Rows[e.NewEditIndex].FindControl（“TextBox1”）；在此代码中，用文本框Id替换文本框1
