如何为每个gridview行中的每个控件设置不同的id

我有一个GridView带有手动定义的列。我有几行（我使用一个按钮添加一行）。我的问题是，同一列中的所有控件都具有相同的ID，因此我无法在“日期”列（称为Fecha）中使用JQuery Datepicker。

我相信我可以使用txtFecha1，txtFecha2等控件ID来添加行按钮来工作（保留旧数据）。但是我应该在哪里设置这些名称？

我应该提一下，我也会想办法让JQuery datepicker在具有相同id的控件上工作，但是许多答案都认为它不起作用，因为datepicker假设我是一个很好的程序员，并且我设置了另一个id对于每个控件。

GridView的代码：

        <asp:GridView CssClass="table table-striped table-bordered table-condensed"
        ID="gvActividades" runat="server" EmptyDataText="Error" AllowPaging="False"
        AutoGenerateColumns="false" OnRowDataBound="gvActividades_OnRowDataBound"
        OnRowDeleting="gvActividades_RowDeleting">
        <Columns>
            <asp:CommandField ShowDeleteButton="True" />
            <asp:TemplateField runat="server" HeaderText="Técnico">
                <ItemTemplate>
                    <asp:DropDownList runat="server" ClientIDMode="Static" class="form-control" ID="cboTecnico">
                    </asp:DropDownList>
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField runat="server" HeaderText="Fecha">
                <ItemTemplate>
                    <asp:TextBox runat="server" ClientIDMode="Static" class="form-control datepicker" ID="txtFecha" />
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField runat="server" HeaderText="Hora de inicio">
                <ItemTemplate>
                    <asp:TextBox runat="server" ClientIDMode="Static" class="form-control" ID="txtHoraInicio" />
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField runat="server" HeaderText="Hora de fin">
                <ItemTemplate>
                    <asp:TextBox runat="server" ClientIDMode="Static" class="form-control" ID="txtHoraFin" />
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField runat="server" HeaderText="Repuesto">
                <ItemTemplate>
                    <asp:DropDownList runat="server" ClientIDMode="Static" class="form-control" ID="cboRepuesto">
                    </asp:DropDownList>
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField runat="server" HeaderText="Cantidad">
                <ItemTemplate>
                    <asp:TextBox runat="server" ClientIDMode="Static" class="form-control" ID="txtCantidad" />
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField runat="server" HeaderText="Descripción">
                <ItemTemplate>
                    <asp:TextBox runat="server" ClientIDMode="Static" class="form-control" ID="txtDescripcion" />
                </ItemTemplate>
            </asp:TemplateField>

        </Columns>
        <SelectedRowStyle CssClass="gvSelectedRowStyle" />
        <PagerStyle CssClass="gvPagerStyle" />
    </asp:GridView>

添加行按钮的代码（按下按钮时调用的方法）：

    protected void cmdAgregarFila_Click(object sender, EventArgs e)
{
    if (null == ViewState["CurrentTable"])
    {
        return;
    }
    int rowIndex = 0;

    DataTable dtCurrentTable = (DataTable)ViewState["CurrentTable"];
    DataRow drCurrentRow = null;
    if (dtCurrentTable.Rows.Count > 0)
    {
        for (int i = 1; i <= dtCurrentTable.Rows.Count; i++)
        {
            DropDownList cboTecnico =
             (DropDownList)gvActividades.Rows[rowIndex].Cells[1].FindControl("cboTecnico");
            TextBox txtFecha =
              (TextBox)gvActividades.Rows[rowIndex].Cells[2].FindControl("txtFecha");
            TextBox txtHoraInicio =
              (TextBox)gvActividades.Rows[rowIndex].Cells[3].FindControl("txtHoraInicio");
            TextBox txtHoraFin =
              (TextBox)gvActividades.Rows[rowIndex].Cells[4].FindControl("txtHoraFin");
            DropDownList cboRepuesto =
          (DropDownList)gvActividades.Rows[rowIndex].Cells[5].FindControl("cboRepuesto");
            TextBox txtCantidad =
              (TextBox)gvActividades.Rows[rowIndex].Cells[6].FindControl("txtCantidad");
            TextBox txtDescripcion =
              (TextBox)gvActividades.Rows[rowIndex].Cells[7].FindControl("txtDescripcion");
            drCurrentRow = dtCurrentTable.NewRow();
            drCurrentRow["RowNumber"] = i + 1;

            dtCurrentTable.Rows[i - 1]["Col1"] = cboTecnico.SelectedValue;
            dtCurrentTable.Rows[i - 1]["Col2"] = txtFecha.Text;
            dtCurrentTable.Rows[i - 1]["Col3"] = txtHoraInicio.Text;
            dtCurrentTable.Rows[i - 1]["Col4"] = txtHoraFin.Text;
            dtCurrentTable.Rows[i - 1]["Col5"] = cboRepuesto.SelectedValue;
            dtCurrentTable.Rows[i - 1]["Col6"] = txtCantidad.Text;
            dtCurrentTable.Rows[i - 1]["Col7"] = txtDescripcion.Text;
            rowIndex++;
        }
        dtCurrentTable.Rows.Add(drCurrentRow);
        ViewState["CurrentTable"] = dtCurrentTable;

        gvActividades.DataSource = dtCurrentTable;
        gvActividades.DataBind();
    }

    SetPreviousData();
}

行添加的其他方法：

protected void Page_Load(object sender, EventArgs e)
{

    if (!Page.IsPostBack)
    {
        FirstGridViewRow();
    }
}

    dt.Columns.Add(new DataColumn("Col5", typeof(string)));
    dt.Columns.Add(new DataColumn("Col6", typeof(string)));
    dt.Columns.Add(new DataColumn("Col7", typeof(string)));
    dr = dt.NewRow();
    dr["RowNumber"] = 1;

    gvActividades.DataBind();
}
