Question

我似乎无法在gridview中获取单元格的值以在存储过程中使用。这是我的aspx：

<asp:GridView ID="gvData" runat="server" AutoGenerateColumns="false" SkinID="GridView" DataKeyNames="Check Config">
            <Columns>
                <asp:BoundField HeaderText="Config ID" DataField="Check Config"></asp:BoundField>
                <asp:BoundField HeaderText="Check Configuration" DataField="Check Configuration" />
                <asp:BoundField HeaderText="Shift" DataField="Shift" />
                <asp:BoundField HeaderText="Earliest Time" DataField="Earliest Time" />
                <asp:BoundField HeaderText="Alarm Time" DataField="Alarm Date" />
                <asp:BoundField HeaderText="Disposition" DataField="Disposition" />
                <asp:TemplateField HeaderText="Disable">
                    <ItemTemplate>
                        <asp:CheckBox runat="server" ID="RowLevelCheckBox" />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

这是我的代码隐藏，其中我试图获取gridview中第一列/单元格的值以获取存储过程参数。在这种情况下，我希望获得“配置ID”的值，但每次都返回0。自从我回到ASP.NET之后已经有一段时间了，但是这个项目需要它。

try
        {
            foreach (GridViewRow dr in gvData.Rows)
            {
                CheckBox chk = (CheckBox)dr.Cells[6].FindControl("RowLevelCheckBox");
                if (chk.Checked)
                {
                    recordCount += 1;
                    int theConfigID = Convert.ToInt32(dr.Cells[0].FindControl("Config ID").ToString());
                    //cancel these alarms in DB 
                    command.Parameters.Add(new SqlParameter("@CHECK_SCHEDULE_ID", theConfigID));
                    command.ExecuteNonQuery();

                    //return status and msg
                    lblStatusMessage.ForeColor = System.Drawing.Color.DarkGreen;
                    lblStatusMessage.Text = string.Format("{0} alarm(s) were successfully cancelled.", recordCount);
                    lblStatusMessage.Visible = true;
                }
            }
        }

Answer 1

怎么样只是dr.Cells [0] .Text？

Answer 2

我建议不要在列名中使用空格，并使用gridview上的DataKeyNames属性来访问id。这样您甚至不必向用户显示id。

foreach(GridViewRow dr in gvData.Rows)
{
    CheckBox chk = (CheckBox)dr.Cells[6].FindControl("RowLevelCheckBox");
    if (chk.Checked)
    {
        recordCount += 1;
        int theConfigID = (int) gvData.DataKeys[dr.RowIndex].Value;
        //cancel these alarms in DB 
        command.Parameters.Add(new SqlParameter("@CHECK_SCHEDULE_ID", theConfigID));
        command.ExecuteNonQuery();

        //return status and msg
        lblStatusMessage.ForeColor = System.Drawing.Color.DarkGreen;
        lblStatusMessage.Text = string.Format("{0} alarm(s) were successfully cancelled.", recordCount);
        lblStatusMessage.Visible = true;
    }
}

需要在gridview中获取单元格的值
