            </tr>
            </table>
            </ItemTemplate>
                    </asp:TemplateColumn>
            </Columns>
            <ItemStyle BackColor="White" />
        </asp:DataGrid>

答案应该是这样的:(在c#后面的代码中)

The Answer Should be Somthing Like This:(in code behind c#)

Label mod = this.DataGrid3.SelectedItem.Cells[3].FindControl Label("model").Text;

推荐答案

这是从Gridview的选定行中找到控件的方法.请注意，您必须使用GridView的OnSelectedIndexChanging事件.

This is how you can find a control from selected row of Gridview. Note that, you have to use OnSelectedIndexChanging event of the GridView.

protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
   {
       Label model = (Label)GridView1.Rows[e.NewSelectedIndex].FindControl("model");
       // Do something

   }

希望对您有所帮助.

I hope this helps you well.

尝试一下:

try this :

Label mod  = (Label)DataGrid3.SelectedRow.Cells[3].FindControl("model"); //just changed the index of cells based on your requirements
        if (mod != null)
        {
            string s = mod.Text;
        }
