Question

我有这段代码：

if (e.CommandName == "Comment")
{
    SqlConnection scn = new SqlConnection(ClsPublic.GetConnectionString());
    SqlCommand scm = new SqlCommand("UPDATE tblImages SET fComment = @fComment WHERE (fId=@fId)", scn);

    string mytext = "";
    foreach (GridViewRow row in GVPictures.Rows)
    {
        mytext = ((RadioButtonList)row.FindControl("RBComment")).SelectedItem.Text;
    }
    scm.Parameters.AddWithValue("@fComment", mytext);
    scm.Parameters.AddWithValue("@fId", e.CommandArgument);
    scn.Open();
    scm.ExecuteNonQuery();
    scn.Close();
}

但是，此代码返回最后一行的值，而不是我选择的行。我能做什么？如何获得选定的行值？

Answer 1

“（（单选按钮列表）e.SelectedRow.FindControl（ ”RBComment“））SelectedValue.Text。要么（（单选按钮列表）e.Row.FindControl（ “RBComment”））SelectedValue.Text;'

通过foreach获取Gridview中的RadioButtonList选择值
