单击 gridview 内的按钮时显示文本框

Question

当单击同一 gridview 的另一个单元格内的按钮并替换复选框的按钮时，我想在 gridview 的单元格内显示一个文本框。

像这样：

在点击编辑按钮之前：

点击按钮后，如下所示：

这是 gridview 的 html

 <asp:GridView runat="server" ID="GdVDocumentosFamilia" CssClass="tableCont tableContInfo genTbl tblCenter yellow" OnRowDataBound="GdVDocumentosFamilia_RowDataBound" AutoGenerateColumns="false"> <Columns> <asp:BoundField DataField="Nombre" /> <asp:BoundField DataField="RelacionFFdE" /> <asp:TemplateField> <ItemTemplate> <asp:Label ID="lblTiene" runat="server" CssClass="labelBoldForm"></asp:Label> <asp:LinkButton runat="server" ID="lnkMod" CommandName="cmdMod" CommandArgument="<%# ((GridViewRow) Container).RowIndex %>" CssClass="btn btn-secondary btn-icon btn-2"> <span class="btn-inner--icon"><i class="far fa-edit"></i></span> </asp:LinkButton> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="PartidaNacimiento" HeaderStyle-CssClass="ocultar" ItemStyle-CssClass="ocultar"/> <asp:BoundField DataField="CUI" /> </Columns> </asp:GridView>

这怎么填：

        public void DocumentoFamilia(DataTable dt)
    {
        foreach (DataRow row in dt.Rows)
        {
             row["CUI"] = String.IsNullOrEmpty(row["CUI"].ToString()) ? "Pendiente" : row["CUI"];
        }
        GdVDocumentosFamilia.Columns[0].HeaderText = "Nombre";
        GdVDocumentosFamilia.Columns[1].HeaderText = "Relación";
        GdVDocumentosFamilia.Columns[2].HeaderText = "Partida de nacimiento/CUI";
        GdVDocumentosFamilia.Columns[4].HeaderText = "Número de CUI";
        GdVDocumentosFamilia.DataSource = dt;
        GdVDocumentosFamilia.DataBind();

        foreach (GridViewRow row in GdVDocumentosFamilia.Rows)
        {
            row.Cells[1].Text = String.IsNullOrEmpty(row.Cells[1].Text) ? "Pendiente" : row.Cells[1].Text;
            row.Cells[1].ForeColor = row.Cells[1].Text == "Pendiente" ? Color.Red : Color.Empty;
            row.Cells[4].ForeColor = row.Cells[4].Text != "Pendiente" ? Color.Empty : Color.Red;
        }
    }

最后这是行数据绑定。

 protected void GdVDocumentosFamilia_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            string tienecui = e.Row.Cells[3].Text;
            if (tienecui != "NO")
            {
                LinkButton lnkMod = e.Row.FindControl("lnkMod") as LinkButton;
                lnkMod.Visible = false;
                Label lblTiene = e.Row.FindControl("lblTiene") as Label;
                lblTiene.Text = "SI";
            }

        }

    }
