在ASP.NET中编辑，选择并显示要标记的选定行 [英] Edit, Select and show selected row to label in ASP.NET

问题描述

你好，

Hello,

http://i.stack.imgur.com/fNHoc.png

因此，当我单击Select时，我想在Label中显示包含一行的所有数据。除了DropdownList之外，我已经设法做到了这一点。当我点击选择时，它只是空的。如上图所示。

P.S。：我没有以编程方式完成此操作。我在.aspx.cs文件中写的唯一代码。

So, when I click Select I want to show in a Label all datas that contain one row. I have managed to make this, except DropdownList. When I click "Select" it's just empty. Like in the picture above.
P.S.: I have not done this programmatically. The only code I've wrote on .aspx.cs file.

protected void GridView_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
    {
        Label1.Text = GridView1.Rows[e.NewSelectedIndex].Cells[1].Text;
        Label2.Text = GridView1.Rows[e.NewSelectedIndex].Cells[2].Text;
        Label3.Text = GridView1.Rows[e.NewSelectedIndex].Cells[3].Text;
    }

推荐答案

在 SelectedIndexChanging 事件中尝试以下代码。

Try below code inside the SelectedIndexChanging Event.

GridViewRow row = GridView1.Rows[e.NewSelectedIndex];
DropDownList ddl = row.FindControl("ddlDropDownList") as DropDownList;
someLabel.Text = ddl.SelectedValue.ToString();

OP的回复



不。它不起作用，但我找到了解决方案。它是：

OP 's reply

Nope. It doesn't work, but I figured out the solution. It is:

Label drpValue = (Label)this.GridView1.Rows[e.NewSelectedIndex].Cells[1].FindControl("Label1");
Lbl1.Text = drpValue.Text;
